Ingredients

Agrimony

Agrimonia eupatoria flowering herb, used in traditional oral and topical herbal preparations.

Aloe Vera Topical Gel

In a randomized study, 0.5% aloe gel applied four times daily produced greater ulcer size reduction than placebo in RAS.

Anise

Pimpinella anisum fruit, commonly called aniseed, used as a spice and in traditional digestive herbal medicines.

Arnica

Arnica montana flower preparations are used externally for localized bruises, sprains, and muscle pain; the canonical relationship is topical and traditional-use only.

Ashwagandha

Withania somnifera root, used in standardized oral extracts and traditional Ayurvedic medicine; evidence for stress outcomes comes mainly from repeated supplementation over weeks rather than single-dose rescue use.

Berberine Alkaloid

A meta-analysis of 17 trials found berberine increased clinical cure rates for diarrhoea versus controls with RR about 1.37 and low heterogeneity.

Botanical Topicals General

A 2025 meta-analysis of eight randomized controlled trials concluded that topical plant-based preparations significantly enhanced skin hydration and overall skin elasticity compared with controls, supporting the general efficacy of botanical topical products for improving skin moisture. The same meta-analysis found no statistically significant effect of botanical preparations on TEWL, net elasticity (R5), or the ratio of elastic recovery to total deformation (R7), indicating that improvements in measured hydration and overall elasticity did not consistently translate into reduced transepidermal water loss.

Butterbur

Petasites hybridus, an herb whose raw material naturally contains potentially toxic pyrrolizidine alkaloids; only appropriately processed PA-free medicinal extracts are relevant to clinical evidence.

Camellia sinensis (tea tree / tea shrub)

Camellia sinensis is the plant used to make green, black, oolong, and other teas. Preparations may be consumed as brewed tea or supplied as concentrated extracts and can contain caffeine and other naturally occurring compounds such as polyphenols.

Camellia Sinensis Acute Diarrhea

A herbal systematic review reports Camellia sinensis preparations reduced stool consistency in acute diarrhoea patients.

Capsaicin

Capsaicin is the pungent capsaicinoid used in standardized topical pain-relief creams. Knee-osteoarthritis evidence is topical and must not be inherited by food, oral cayenne supplements, or homemade rubs.

Caraway

Carum carvi fruit, commonly called caraway seed, used as a culinary spice and in traditional digestive herbal medicines.

Chasteberry

Vitex agnus-castus

Vitex agnus-castus fruit preparations used for premenstrual symptoms. Evidence is preparation-specific and should not be generalized to teas, whole berries, tinctures, powders, or recipes.

Cinnamon

Cinnamomum bark used as a culinary spice and in oral supplement preparations.

Commiphora Myrrh Topical Gel

The same trial reported 0.5% myrrh gel yielded larger pain intensity reduction than placebo in RAS ulcers.

Dried Bilberry Fruit

Dried ripe fruit of Vaccinium myrtillus, distinct from fresh bilberry extracts used for other indications.

Echinacea

Echinacea has mixed and inconsistent evidence for common-cold prevention or treatment, with no clear, reliable benefit established across studies. Echinacea is traditionally used for upper-respiratory infections, including the common cold.

Elderberry

Elderberry has limited clinical evidence suggesting possible symptom benefit in viral respiratory illness, but the evidence base for common cold specifically remains small and uncertain.

Fennel

Foeniculum vulgare fruit, commonly called fennel seed, used as a culinary spice and in oral herbal medicines.

Ginger

Zingiber officinale

Zingiber officinale rhizome, used as food and in oral supplements; exercise-soreness evidence is based on repeated measured intake and must not be generalized to an arbitrary tea or recipe dose.

Honey

A familiar food ingredient commonly used in warm drinks and other home preparations.

Ivy Leaf

Hedera helix leaf used in standardized medicinal extracts for productive cough.

Lemon Balm

Melissa officinalis leaf, traditionally used for mild mental stress and studied in several standardized oral extracts for acute mood and cognitive-stress outcomes.

Licorice Root

The root of Glycyrrhiza species, used traditionally in cough-and-cold and digestive preparations.

Magnesium

An essential mineral studied in oral supplemental doses for migraine prevention; evidence is limited and the studied doses can exceed general supplemental intake limits.

Marshmallow Root

Althaea officinalis root, traditionally used in soothing preparations for irritated mucous membranes.

Matricaria Chamomilla Topical

A randomized triple-blind trial found chamomile tincture mouthwash significantly reduced number of RAS ulcers and pain versus placebo.

Menthol

A cooling aromatic compound found naturally in mint oils and also manufactured for use in lozenges and topical products.

Multi Herb Topical Cream17 Composition Uncertain

A randomized assessor-blinded 4-week trial of a topical cream containing 17% herbal extract (Cream17) in 33 subjects showed significant reductions in transepidermal water loss (TEWL) and significant increases in skin water content compared with untreated control, indicating improved skin barrier function relevant to dry-skin conditions. In the Cream17 trial, topical application significantly lowered itch scores at 2 and 4 weeks compared with untreated control, aligning with symptomatic relief of pruritus associated with dry skin.

Oral Multi Herb Antiaging Combinations Hydration Related

A systematic review of 12 randomized trials on oral herbal supplements for skin aging reported improvements in skin hydration and elasticity among adults, suggesting potential systemic benefits for skin moisture, though trials targeted cosmetic aging rather than clinical xerosis and used diverse multi-herb formulations.

Pelargonium

Pelargonium sidoides root used in standardized herbal medicinal products for respiratory and common-cold symptoms.

Pelargonium Sidoides

Pelargonium sidoides has some evidence for acute respiratory infections, but the evidence specifically for the common cold is not definitive from the sources reviewed here.

Peppermint

Mentha x piperita leaf, used in herbal teas and oral digestive preparations; peppermint essential oil is a distinct, more concentrated preparation.

Peppermint leaf

Mentha x piperita L.

In IBS patients, enteric-coated peppermint oil capsules significantly reduced abdominal distension and flatulence compared with placebo, indicating carminative efficacy for bloating-related symptoms in this population. A small-intestinal release peppermint oil formulation produced a statistically significant improvement in abdominal bloating or distension.

Peppermint Oil

Concentrated Mentha x piperita essential oil. IBS evidence is specific to oral enteric-coated capsules and must not be inherited by peppermint tea, leaf, food, aromatherapy, or topical oil.

Polyherbal Oral Antiaging Combination Hydration Related

A randomized double-blind placebo-controlled study of an optimized multiherbal oral combination for anti-skin aging demonstrated improvements in skin moisture and barrier-related parameters, but its primary endpoint was aging rather than treatment of dry-skin conditions such as xerosis.

Polyherbal Topical Lip Hydrant Composition Uncertain

A randomized double-blind controlled trial of a polyherbal lip hydrant in 66 adults with dry and chapped lips found that the novel product provided effective moisturizing treatment, improving lip dryness, though this focuses on localized lip xerosis and the exact herbal composition is not fully detailed.

Polyherbal Topical Moisturizer Composition Uncertain

A clinical regimen study reported that participants using a moisturizer-containing skin care regimen experienced significantly greater improvements in clinical dry-skin scores and decreased dryness/pruritus compared with controls, but the moisturizer formulation included multiple ingredients and is not strictly an isolated herbal preparation.

Probiotics General Acute Diarrhea Children

A narrative summary of probiotic trials concluded probiotics, with rehydration therapy, clearly shorten duration and reduce stool frequency in acute infectious diarrhoea.

Psidium Guajava Herbal Gel

A single-blind randomized study found Psidium guajava herbal gel reduced RAS ulcer size and pain compared with no treatment.

Psyllium

Psyllium (Plantago ovata/ispaghula) intake reduces LDL cholesterol and total cholesterol in randomized controlled trials and meta-analyses.

Psyllium Plantago Ovata Husk

Four randomized crossover clinical trials support the efficacy of psyllium in reducing stool liquidity or frequency in acute and chronic diarrhoea.

Rhubarb (Dried Root)

Rhubarb is a plant whose dried root is used in traditional medicine.

Sage

Salvia officinalis leaf, used as a culinary herb and in medicinal throat preparations.

Senna Leaf

Senna leaf preparations can be used short term for occasional constipation. The AGA guideline suggests senna over management without senna in adults with chronic idiopathic constipation, but the certainty of evidence is low.

Thyme

A widely used culinary herb that also has a long history of use in cough-and-cold preparations.

Tormentil

Potentilla erecta rhizome, traditionally used in astringent oral preparations.

Turmeric

Turmeric is a bright yellow spice from the ginger family that contains an active compound called curcumin, which may help reduce joint pain and stiffness in osteoarthritis by blocking inflammatory pathways.

Valerian root

Valerian root is the dried underground part of Valeriana officinalis, a plant traditionally used in European herbal medicine for mild nervous tension and sleep problems.

Zinc

Zinc lozenges can reduce common-cold duration when started early after symptom onset.

Zinc (oral lozenges)

Zinc lozenges are oral supplements that dissolve slowly in the mouth, releasing ionic zinc to the throat and upper respiratory tract.
