You've heard that Cosmic Hue works.

You've read the testimonials from people who've transformed their gut health.

But if you're the type of person who needs to see the research before you try anything, you're in the right place.

This page isn't marketing. It's a comprehensive look at the clinical evidence behind each of the seven plants in Cosmic Hue: marshmallow root, cat's claw, echinacea, astragalus root, ashwagandha root, stinging nettle and fennel seeds.

When I formulated Cosmic Hue during my recovery from Crohn's Disease, I didn't just rely on traditional wisdom. I spent years studying clinical trials, looking at how these plants work in the body, and testing combinations in my own kitchen.

Below, you'll find over 100 peer-reviewed studies exploring these plants in human trials, animal models, laboratory research, meta-analyses, and reviews.

Note: The studies below were conducted on the individual ingredients found in Cosmic Hue, not on our specific blend. We’ve compiled this research to show the powerful mechanisms behind these plants, but this information is for informational purposes only.

Summary of Findings

Across human clinical trials, systematic reviews, and laboratory research, the seven plants in Cosmic Hue have been shown to:

Support digestive health and gut lining integrity. Multiple studies show these plants can soothe irritated gut tissue, support the protective mucous layer, and help maintain a healthy gut.

Regulate inflammation throughout the body. Research demonstrates these plants can influence key inflammatory pathways, helping the body maintain a balanced immune response rather than chronic inflammation.

Strengthen immune function. Several ingredients have been studied for their ability to support both rapid immune response and long-term immune resilience, particularly during periods of stress.

Help the body adapt to stress and support recovery. Clinical trials on adaptogens like ashwagandha show measurable reductions in stress hormones and improvements in stress-related symptoms.

Support natural energy and mental clarity. Human studies link several of these plants to improvements in fatigue, cognitive function, and overall vitality without the need for stimulants.

Cosmic Hue was formulated to bring these benefits together in one daily ritual.

Each ingredient targets different aspects of gut health, stress regulation, and immune support, creating a synergistic blend that works with your body's natural processes.

Fennel Seeds

Fennel (Foeniculum vulgare) is a well-known culinary herb and medicinal plant used globally in traditional systems of medicine. Its seeds and essential oil are particularly valued.

Modern clinical research has focused on fennel's long-standing reputation for supporting digestive health, managing women's health concerns, and providing antioxidant benefits.

Supports Digestive Function and Motility

Heated fennel therapy has been shown to facilitate the recovery of gastrointestinal function after complex abdominal surgery [1]. A study found it significantly reduced the time to first flatus and defecation and helped relieve postoperative abdominal distension [1].

When combined with curcumin, fennel essential oil significantly improved symptoms and quality of life in patients with Irritable Bowel Syndrome (IBS) [4]. A 30-day study noted a 50.05% decrease in symptom severity scores, compared to just 26.12% for the placebo group [4].

A "real-life" study of 211 patients confirmed that a combination of turmeric and essential fennel oil improved both symptoms and quality of life across all IBS subtypes (constipation-predominant, diarrhoea-predominant, and mixed) [3].

Fennel seed oil emulsion appears superior to placebo for reducing the intensity of infantile colic [5]. One randomised, placebo-controlled study found that fennel oil eliminated colic in 65% of infants, a rate significantly higher than the 23.7% observed in the placebo group [5].

Helps Women's Health Concerns

Fennel is studied as an effective herbal remedy for menstrual pain (primary dysmenorrhea) [7]. A systematic review and meta-analysis of 12 trials concluded that fennel's effect in alleviating pain is similar to that of conventional drug therapies [6].

One clinical trial directly compared fennel essence to mefenamic acid, a common NSAID, and found that both effectively relieved menstrual pain, concluding fennel can be a safe and effective alternative [8].

Fennel has been shown to effectively reduce symptoms in postmenopausal women [9, 10]. A triple-blind, placebo-controlled trial where women received 100 mg fennel capsules twice daily showed a significant decrease in the total Menopause Rating Scale (MRS) score compared to placebo [9].

A 5% fennel vaginal cream was shown to be an effective means to manage the symptoms of vaginal atrophy in postmenopausal women [12]. After 8 weeks, the fennel group showed significant improvements in vaginal pH and cellular maturation [12].

Exhibits Antioxidant Properties

Both water and ethanol extracts of fennel seeds have demonstrated strong antioxidant activity in vitro [14]. One study found that a water extract exhibited 99.1% inhibition of peroxidation, an activity level greater than the same dose of the standard antioxidant α-tocopherol [14].

Essential oils from various parts of the fennel plant, including the seeds, show antimicrobial activities against various Gram-positive and Gram-negative bacteria, as well as fungi [13, 15, 16].

Fennel seed oil demonstrated the highest antibacterial effect against Staphylococcus aureus, creating a 30 mm inhibition zone in one test [13].

Supports Metabolic Health

Research in animal models suggests fennel may have benefits for metabolic health. In mice, fennel extract was associated with a significant decrease in cholesterol, triglycerides, and LDL, as well as a significant increase in beneficial HDL [17].

Studies in diabetic rats suggest fennel may possess anti-hyperglycemic effects. Both fennel essential oil and fennel leaf aqueous extract were found to significantly reduce blood glucose levels [19, 20].

In human studies, a trial on postmenopausal women found short-term fennel treatment did not cause a significant change in total cholesterol or LDL, but it did show a "significant borderline improvement" in beneficial HDL [18].

Ashwagandha Root

Ashwagandha (Withania somnifera) is a prominent herb in Ayurvedic medicine, where it is used as an adaptogen to combat stress and enhance general wellbeing. It is often described as a "rasayana" (rejuvenator) and traditionally used to aid memory, improve endurance, and promote longevity.

Modern clinical studies are investigating these traditional uses, focusing on its effects on stress, sleep, cognition, and physical performance.

Supports Stress and Anxiety Reduction

Ashwagandha is widely studied for its role in managing stress, anxiety, and related psychosomatic disorders [2, 5].

A meta-analysis of 12 randomised controlled trials (RCTs) involving 1,002 participants found that Ashwagandha supplementation significantly reduced both anxiety (SMD: -1.55) and stress levels (SMD: -1.75) compared to placebo [1].

Another meta-analysis of 9 RCTs confirmed a significant reduction in scores on the Hamilton Anxiety Scale (HAS) and the Perceived Stress Scale (PSS) [2].

Several studies show Ashwagandha supplementation is associated with significantly greater reductions in the stress hormone cortisol [2, 3, 5, 11]. One 60-day study noted a substantial reduction in serum cortisol in the group taking 300 mg twice daily [5].

Improves Sleep Quality and Insomnia

The herb has traditionally been used to support more restful sleep, and research suggests it is beneficial for improving sleep in adults, particularly those with insomnia [6, 8].

A systematic review and meta-analysis of 5 RCTs (400 participants) found that Ashwagandha extract had a significant beneficial effect on overall sleep [6]. The effects were more prominent at doses of 600 mg/day or more and for durations of at least 8 weeks.

In a 6-week study of 144 healthy adults with non-restorative sleep, the group receiving 120 mg of Ashwagandha extract reported a 72% increase in self-reported sleep quality, compared to only 29% in the placebo group [7].

The same study used actigraphy to confirm significant improvements in sleep efficiency, total sleep time, and sleep latency [7]. Supplementation has also been shown to improve mental alertness upon rising [6, 8].

Enhances Cognitive Function and Mood

Ashwagandha has traditionally been used to aid memory and cognition [10]. Clinical studies suggest it may improve cognitive tasks, executive function, attention, and reaction time [10].

In a 90-day study of stressed adults, a 300 mg daily dose of Ashwagandha significantly improved recall memory and reduced the error rate on cognitive tests compared to placebo [11].

The same study noted significantly higher scores on the Oxford Happiness Questionnaire, indicating improved psychological well-being [11].

Even acute (single-dose) supplementation has been shown to improve working memory, sustain attention, and help prevent mental fatigue in cognitive tasks [9, 12].

Aids Athletic Performance and Recovery

Ashwagandha is associated with improving physical performance, including strength, endurance, and recovery [18].

In an 8-week study, healthy young men in a resistance-training program who took 300 mg of Ashwagandha root extract twice daily had significantly greater increases in muscle strength on the bench-press and leg-extension compared to the placebo group [13].

The supplemented group also showed a significantly greater increase in muscle size at the arms and chest, and a greater reduction in body fat percentage [13].

For endurance, a meta-analysis found that Ashwagandha supplementation significantly enhances VO2max (a measure of cardiorespiratory endurance) in both athletes and healthy adults [17].

The herb also appears to aid recovery. Studies note a significant reduction in markers of exercise-induced muscle damage (like serum creatine kinase) [13] and improved scores on recovery and stress questionnaires for athletes [14].

Stinging Nettle

Stinging Nettle (Urtica dioica), is a plant with a long history of use in traditional herbal medicine. It has been used to address a wide variety of ailments, from joint pain to seasonal allergies.

Modern scientific research is now investigating these traditional uses, focusing on its potential benefits for prostate health, inflammation, blood sugar regulation, and allergic rhinitis.

Supports Prostate and Urinary Health

Stinging Nettle root is frequently studied for its potential to relieve symptoms of benign prostatic hyperplasia (BPH), or an enlarged prostate.

A 6-month, double-blind, placebo-controlled study involving 620 patients found that Urtica dioica provided significant relief for lower urinary tract symptoms (LUTS) compared to a placebo [1].

In that study, 81% of the nettle group reported improved symptoms, versus only 16% of the placebo group. The International Prostate Symptom Score (IPSS) also dropped from 19.8 to 11.8 in the nettle group, while the placebo group only saw a minor drop from 19.2 to 17.7 [1].

The same 2005 study noted improvements in urinary function. A modest decrease in prostate volume was also seen in the nettle group, from 40.1 cc down to 36.3 cc [1].

A 2025 systematic review of 6 clinical trials (totalling 1,210 patients) also found that Urtica dioica slightly improved BPH symptoms and led to a reduction in prostate-specific antigen (PSA) levels [3].

Provides Anti-inflammatory Support

Multiple studies suggest Urtica dioica has strong anti-inflammatory properties that may help with conditions like arthritis.

Research indicates nettle extract may work by inhibiting NF-kappaB, a primary transcription factor responsible for activating many pro-inflammatory genes [9].

An ex-vivo study using human blood found that a nettle extract significantly inhibited the secretion of key inflammatory cytokines in a dose-dependent manner. At its highest concentration, it reduced tumour necrosis factor-alpha (TNF-alpha) by 50.8% and interleukin-1 beta (IL-1 beta) by 99.7% [8].

In a 3-month clinical trial for Rheumatoid Arthritis (RA), patients taking Urtica dioica showed significant improvements in disease activity scores (DAS28) and reductions in inflammatory markers like C Reactive Protein (CRP) and Rheumatoid Factor (RF) compared to placebo [6].

A pilot study on acute arthritis found that stewed nettle leaf combined with a low 50 mg dose of diclofenac (an NSAID) produced a 70% improvement in symptoms, which was comparable to a high 200 mg dose of the drug alone [5].

For osteoarthritis, a randomised trial found that daily topical application of stinging nettle leaf to the painful area provided significantly greater reductions in pain and disability scores compared to a placebo [4].

Helps Regulate Blood Sugar Levels

Meta-analyses and clinical trials have investigated nettle's effect on glycemic control in patients with Type 2 Diabetes Mellitus (T2DM).

A 2019 meta-analysis of 8 clinical trials (401 participants) found that nettle supplementation led to a significant reduction in Fasting Blood Sugar (FBS) concentrations, with an average reduction of 18.01 mg/dl [10].

A separate 2021 meta-analysis of 13 trials confirmed this, reporting a significant decrease in Fasting Blood Glucose of 17.17 mg/dl [11].

The 2021 meta-analysis also found that Urtica dioica consumption significantly decreased Hemoglobin A1c (HbA1c) levels by an average of 0.93% [11].

This is supported by a 3-month clinical trial on patients with advanced T2DM, which found that 500 mg of nettle extract three times a day significantly lowered fasting glucose, 2-hour postprandial glucose, and HbA1c compared with placebo [12].

Animal studies suggest nettle may work by improving plasma glucose homeostasis and enhancing skeletal muscle insulin sensitivity [13, 14].

Relieves Allergy Symptoms

Stinging Nettle is a traditional remedy for seasonal allergies (allergic rhinitis), and modern research has explored its mechanisms.

In vitro research provides a mechanistic basis for its use, showing that nettle extract can act as an antagonist against the Histamine-1 (H(1)) receptor, which is the same receptor targeted by many allergy medications [17].

The same in vitro study found it inhibits mast cell tryptase, which prevents the release of pro-inflammatory mediators that cause hay fever symptoms [17].

In a randomised, double-blind study on allergic rhinitis, a freeze-dried preparation of Urtica dioica was rated higher than placebo in global assessments for symptom relief [15].

A 2017 clinical trial found that patients taking nettle extract saw a significant improvement in their allergy symptom severity and a significant reduction in nasal smear eosinophil count, a key inflammatory cell in allergic rhinitis [16].

Astragalus Root

Astragalus (Astragalus membranaceus) is a foundational herb in Traditional Chinese Medicine (TCM). It is traditionally used to support recovery from various conditions and is known for its potent active compounds.

Modern research is investigating these compounds for their significant pharmacological actions, particularly in immune regulation, cardiovascular health, and as a supportive therapy in cancer treatment.

Regulates Immune Function

Astragalus is widely studied for its immunomodulatory effects. The main active components, Astragalus polysaccharides (APS), are believed to promote the repair and regulation of the immune system.

A 2023 systematic review and meta-analysis of 19 human studies (1,094 participants) found that Astragalus intervention significantly enhanced cellular immune markers, specifically by increasing CD3 levels and the CD4/CD8 ratio [3].

The same meta-analysis concluded that Astragalus "demonstrated a significant reduction in proinflammatory cytokines", suggesting a powerful regulatory effect [3].

In a study of 62 patients with congestive heart failure, Astragalus injection was found to improve immune function by significantly increasing the CD4 level and the CD4/CD8 ratio [9].

In vitro studies show that Astragalus extract can activate macrophages (a type of white blood cell) to increase their migration and release of immune response mediators, which may "improve host defences to avoid infections" [4].

Supports Cardiovascular and Heart Health

Key compounds in Astragalus, particularly Astragaloside IV (AS-IV), have been the focus of extensive research for their protective effects on the heart and blood vessels.

AS-IV has been shown in reviews to protect the myocardium (heart muscle) through multiple pathways, including anti-oxidative stress, anti-inflammatory effects, improving myocardial energy metabolism, and improving microcirculation [6].

The same review notes that AS-IV also helps protect vascular endothelial cells (the lining of blood vessels), relax blood vessels, and stabilise atherosclerotic plaques [6].

A major meta-analysis of 19 randomised controlled trials (RCTs) with 1,565 patients with heart failure found that combining Astragalus with conventional treatment significantly improved heart function [7].

This meta-analysis showed the combination therapy increased left ventricular ejection fraction (LVEF) by an average of 5.82% and increased the 6-minute walking distance by 67.62 meters [7].

In a separate study of 45 patients with chronic heart failure, the group receiving Astragalus granules had a significantly higher LVEF (64.45% vs. 56.03%) and longer 6-minute walk distance (446.97 m vs. 345.40 m) than the control group [10].

A systematic review of 6 RCTs (639 participants) also found that Astragalus injection combined with conventional treatment had a "significantly higher" total effective rate for treating viral myocarditis [8].

Provides Adjunctive Cancer Support

Astragalus has been extensively studied as an adjunctive therapy, meaning it is used alongside conventional treatments like chemotherapy to support patient outcomes and quality of life.

Astragalus polysaccharides (APS) are noted for potential anti-tumour actions, which include enhancing immunity, inducing apoptosis of tumour cells and inhibiting the proliferation and transfer of tumour cells [1].

A large meta-analysis of 65 RCTs enrolling 4,751 patients with advanced non-small-cell lung cancer (NSCLC) found that adding Astragalus-based herbal treatment to platinum-based chemotherapy improved outcomes [11].

In this analysis, a composite endpoint of "any tumour treatment response" showed a pooled relative risk (RR) of 1.35 in favour of the herbal treatment. It also improved 12-month survival rates [11]. A separate meta-analysis confirmed this, finding a RR of 1.34 for improved tumor response [12].

In a study of 120 tumour patients undergoing chemotherapy, the group receiving Astragalus injection had a "lesser decrease of peripheral WBC and platelet count" and a significantly increased CD4/CD8 ratio, suggesting it can "decrease the toxic-adverse effect of chemotherapy" [13].

A meta-analysis of 27 RCTs (1,843 colorectal cancer patients) identified Astragalus membranaceus as one of six key plants associated with "significant reductions in CINV" (chemotherapy-induced nausea and vomiting) [14].

Echinacea

Echinacea (Echinacea), a plant originally used by Native Americans to soothe respiratory infections, is one of the most commonly used herbal products worldwide. It has been traditionally used to support the immune system during infections.

Modern research is investigating its potent immunomodulating and anti-inflammatory properties, focusing on its ability to support the immune system and manage symptoms of respiratory infections.

Supports Immune Function

Echinacea is identified as a "wide-spectrum immunomodulator" that stimulates both the body's innate and adaptive immune responses [1].

In a study on human macrophages, Echinacea purpurea juice stimulated the production of key immune-activating cytokines at very low concentrations, an effect consistent with an antiviral response [2].

It has been shown to increase the percentage of crucial immune cells, including natural killer (NK) cells and B-lymphocytes, and to significantly enhance the body's overall antibody response [1].

In a mouse model of immunosuppression, a standardised Echinacea purpurea extract (with 4% chicoric acid) increased natural killer (NK) cell activity by 24.6% and increased the phagocytic index (macrophage activity) by 28.03% [4].

The same extract also increased nitric oxide production in immune cells by 30.76-fold to 39.07-fold, a key part of the immune response [4].

Echinacea extracts have also been found to stimulate the expression of numerous immune response genes in human bronchial epithelial cells [3].

Reduces the Duration of the Common Cold

Multiple clinical studies and a major meta-analysis support Echinacea's role in both reducing the risk and reducing the duration of the common cold.

A meta-analysis of 14 clinical studies found that Echinacea decreased the odds of developing the common cold by 58% [5].

The same meta-analysis concluded that Echinacea supplementation reduced the duration of a cold by an average of 1.4 days [5].

In a large, 4-month clinical trial with 755 healthy subjects, prophylactic (preventive) use of Echinacea purpurea reduced the total number of cold episodes, the total number of days spent sick, and the need for pain-killer medication [6].

The trial noted that Echinacea was particularly effective at inhibiting virally confirmed colds (especially from enveloped viruses) and showed maximal effects against recurrent infections [6].

In a cell study, Echinacea extracts tended to "neutralise the effects of the rhinovirus" (a primary cause of the common cold) on human bronchial cells [3].

Provides Anti-inflammatory Action

Compounds within Echinacea, such as alkylamides and chicoric acid, have been shown to help manage inflammation by regulating key biological pathways.

A systematic review concluded that Echinacea supplementation is associated with a decrease in pro-inflammatory cytokines, while also promoting an increase in an anti-inflammatory cytokine [12].

Several other studies confirm that Echinacea extracts can inhibit the release of key inflammatory drivers [1, 7, 8, 10].

Alkylamides, a key active compound, exert anti-inflammatory activity by down regulating major inflammatory signalling pathways [7].

In a rat model of rheumatoid arthritis, chicoric acid extract (CAE) from Echinacea purpurea significantly decreased paw swelling and reduced serum levels of inflammatory markers [8].

A pilot study in humans with knee osteoarthritis (who were poor responders to NSAIDs) found that supplementation with Echinacea angustifolia (and ginger) for 30 days resulted in a significant improvement in pain scores [11].

Cat's Claw

Cat's Claw (Uncaria tomentosa) is a medicinal vine from the Amazon rainforest, traditionally used to address inflammatory disorders, including arthritis, gastritis, and osteoarthritis.

Modern research is focused on its anti-inflammatory and immunomodulating properties, which are linked to its ability to inhibit pro-inflammatory mediators.

Provides Anti-inflammatory Action

Cat's Claw is widely studied for its ability to target and regulate key pathways in the body's inflammatory response.

The primary mechanism for its anti-inflammatory action appears to be its ability to suppress the synthesis of TNF-alpha (Tumor Necrosis Factor-alpha), a key inflammatory driver [1, 3, 6].

In in vitro studies on macrophage cells, Cat's Claw was shown to be a "remarkably potent inhibitor" of TNF-alpha, suppressing its production by approximately 65-85% [3].

Mitraphylline, a major active alkaloid in the bark, was tested in vivo and found to inhibit around 50% of the release of several key inflammatory interleukins and TNF-α. This activity was described as "similar to dexamethasone," a common anti-inflammatory drug [10].

In vivo, oral pretreatment with Uncaria tomentosa was shown to protect against indomethacin-induced gastritis by preventing the expression of TNF-alpha mRNA [4].

Supports Arthritis and Joint Health

The anti-inflammatory properties of Cat's Claw have been directly studied for their benefits in managing symptoms of both osteoarthritis and rheumatoid arthritis [2].

For example, a 4-week, placebo-controlled trial involving 45 patients with osteoarthritis of the knee found that Cat's Claw significantly reduced pain associated with activity [6].

The benefits for osteoarthritis pain relief were reported to occur quickly, with symptom relief evident within the first week of therapy [6, 7].

Cat's Claw has also demonstrated a "modest benefit" for rheumatoid arthritis.

A 24-week, double-blind, placebo-controlled study found that the group taking the extract experienced a 53.2% reduction in the number of painful joints, compared to only 24.1% in the placebo group [8].

Modulates the Immune System

Cat's Claw is known as a "non-specific immunomodulating agent" and has been shown to modulate "distinct patterns of the immune system" in a dose-dependent manner [2, 12].

In a human volunteer study, daily supplementation with a specialised water-soluble Cat's Claw extract for 6 consecutive weeks significantly elevated white blood cells with no observed toxicity [11].

In vivo studies support this, showing that Cat's Claw extract can increase the number of T helper lymphocytes and B lymphocytes [12].

The extract has also been shown in animal models to significantly increase lymphocyte proliferation stimulated by PHA (a mitogen), demonstrating a stimulatory effect on the adaptive immune system [11].

Marshmallow Root

Marshmallow root (Althaea officinalis) has been used in traditional medicine for centuries and is now being studied for its potent therapeutic properties. The benefits are largely attributed to its active compounds, including mucilage polysaccharides and flavonoids.

Supports Gastrointestinal Health

Althaea officinalis is traditionally used to manage gastrointestinal disorders and soothe the stomach lining [1].

In an animal study, oral administration of Althaea officinalis extract for 14 days protected against pyloric-ligation/indomethacin-induced gastric ulcers [6].

This protective effect is likely due to its antioxidant properties and its ability to promote protective mucin while suppressing pro-inflammatory cytokines [6].

Soothes Coughs and Irritated Membranes

The root is also known for its antitussive (cough-suppressing) effects and to relieve conditions like chronic cough, sore throat, and bronchitis [1].

The medicinal effects are linked to mucilaginous polysaccharides that form a protective, "mucin-like" film on inflamed mucosal surfaces [2, 4].

This soothing layer reduces irritation, which supports faster regeneration and defence mechanisms in the respiratory tract [2].

Provides Potent Anti-inflammatory Action

In an in vitro study on human macrophage cells, marshmallow root extract inhibited the release of pro-inflammatory markers [2].

The study found the root's anti-inflammatory effects were "similar or even better" than those of diclofenac, a standard reference drug [2].

The root's active compounds stimulate the release of cytokines from monocytes, demonstrating potential anti-inflammatory activity [3].

Aids in Skin Health & Tissue Regeneration

Aqueous extracts from the root have been shown to stimulate the cell viability and proliferation of human epithelial cells in vitro [4].

This finding scientifically supports the traditional use of marshmallow for treating irritated tissues and supporting regeneration [4].

An ointment containing 20% aqueous marshmallow root extract was shown in an in vivo model to reduce skin irritation induced by UV radiation [3].

It has been traditionally used externally for skin conditions like eczema and dermatitis [3].

Exhibits Significant Antioxidant Effects

In vitro, marshmallow root extract was able to protect human macrophage cells against cytotoxicity and oxidative stress (ROS production) induced by hydrogen peroxide [2].

This antioxidant capability is a key mechanism thought to be responsible for its gastroprotective effects [6].

Frequently Asked Questions

Why aren't there studies on Cosmic Hue?

Running full-scale clinical trials on a specific herbal blend costs hundreds of thousands of pounds and typically takes years. These trials are usually funded by pharmaceutical companies developing patentable drugs, not food-based herbal products.
