How to use this page

This is the starting map to the Ayurvedic herbs on AlternativeMed.com. Each herb below has its own guide that separates the traditional description (what classical texts and practitioners say) from the research (what trials and reviews measured) and from safety and product quality. Evidence labels: promising but limited, mixed, insufficient evidence, no good evidence of benefit, traditional use only, evidence of harm.

Two things to know first. The US National Center for Complementary and Integrative Health says few well-designed trials and reviews suggest Ayurvedic approaches are effective, so most labels below are cautious. [3] And one Ayurvedic name can point to more than one plant: "brahmi" corresponds to both Bacopa monnieri and Centella asiatica, so check the Latin name on any label. [4]

The six herbs written up in detail

Herb (guide)Traditional descriptionWhat research showsMain caution
Ashwagandha (Withania somnifera)Called a rasayana; classical texts describe it as strength-giving and nourishing. [5] [6]Stress and sleep: promising but limited. Many other uses: insufficient evidence. [7] [8]Liver injury reports; avoid in pregnancy and breastfeeding; thyroid and medicine interactions. [9] [10]
Turmeric (haridra)Recorded in the Charaka Samhita; considered helpful for appetite, bowel movements and bile flow. [11] [12]Knee osteoarthritis: promising but limited. Most other uses: insufficient evidence. [13]Liver damage with highly bioavailable products; lead-adulterated spice. [14] [15]
A medhya rasayana for the mind in the Charaka Samhita. [16]Some memory and attention measures: promising but limited. [17] [18]Stomach upset; thyroid and medicine interactions; pregnancy data lacking. [19] [20]
An Ayurvedic and traditional Chinese herb; shares the name brahmi. [21]Cognition: no good evidence of benefit. Leg vein symptoms: promising but limited. [22] [23]Liver injury case reports; not advised in pregnancy or under 18 in the EU monograph. [24] [25]
Shatavari (Asparagus racemosus)A women's health and lactation herb. [26]Small trials for milk supply, menopause and PCOS: promising but limited to insufficient. [27] [28]Little verified safety data for pregnancy or hormone-sensitive conditions.
Triphala (see below)An Ayurvedic herbal combination.Gum inflammation rinse and blood fats: promising but limited.Little data on pregnancy or medicine interactions.

Triphala in brief

Triphala is an Ayurvedic herbal combination. Two systematic reviews give a flavor of the research. A review of seven trials found triphala mouthwash had equal clinical efficacy to chlorhexidine mouthwash for plaque-related gum inflammation, though the trials differed widely from each other. [29] [30] [31] A review of 12 trials (749 patients) reported lower LDL cholesterol, total cholesterol and triglycerides in 6 studies, and lower fasting glucose in people with diabetes but not in people without it. [32] [33] [34] The reviewers asked for large, well-designed trials, and no serious adverse events were reported in the trials they reviewed. [35] [36] That says little about long-term or high-dose use. See the full triphala guide.

Before using any herb

Frequently asked questions

Which Ayurvedic herb has the best evidence?

No Ayurvedic herb has strong, consistent evidence across uses. The best-supported claims are limited ones, such as ashwagandha for stress and sleep scores and turmeric for knee osteoarthritis, both labeled promising but limited. [7] [39]

Are Ayurvedic herbs safer because they are natural or traditional?

No. Ashwagandha, turmeric and gotu kola have liver injury reports, and some Ayurvedic products contain metals. [9] [14] [24] [1]

Is "brahmi" always bacopa?

No. Brahmi corresponds to two plants, Bacopa monnieri and Centella asiatica (gotu kola), so check the Latin name. [4]

How common is metal contamination?

A study published in 2008 analyzed 193 Ayurvedic products, [40] bought online in 2005, [41] and found that 20.7% contained detectable lead, mercury or arsenic. [2] Current products may differ, but it shows why quality matters.

Can I take these herbs instead of my medicine?

No. Do not stop or replace a prescribed medicine with an herb. Talk with your prescriber first. [38]

Safety first
An Ayurvedic herb is a medicine-strength plant, not a harmless food. Several have liver injury reports, some are not advised in pregnancy, and some products have been found to contain lead, mercury or arsenic. [1] [2] If you take prescribed medicines, are pregnant or breastfeeding, have liver or thyroid disease, or are planning surgery, ask a doctor or pharmacist before using any of them. If you have yellow skin or eyes, dark urine or strong itching, stop the product and get medical help. In the US, Poison Help is 1-800-222-1222 and the emergency number is 911. This page is information only. It gives no doses and does not tell you which herb to take.
