Acidity, acid reflux and gastritis: what Ayurveda offers

Curcumin eased indigestion more than placebo in one small trial. We found no trial of Ayurveda for reflux disease or gastritis itself.

Anxiety and sleep problems: what Ayurveda offers

Ashwagandha extracts improved sleep a little and lowered stress scores in short trials. They were not trials in diagnosed anxiety disorder.

Hair loss and hair fall: what Ayurveda offers

One industry-sponsored trial found an ashwagandha scalp serum added a few hairs over 75 days. We found no trial of Ayurvedic hair oils.

IBS (irritable bowel syndrome): what Ayurveda offers

The one placebo-controlled trial of an Ayurvedic herbal mix in IBS found no benefit. A whole-system programme beat a single powder in another.

Migraine: what Ayurveda offers

One small trial found a curcumin supplement eased migraine attacks over eight weeks. We found no trial of a classical Ayurvedic treatment.

Osteoarthritis and knee pain: what Ayurveda offers

One boswellia extract and two Indian formulations eased knee pain in trials. The evidence is uneven, and one trial found raised liver enzymes.

PCOS and PCOD: what Ayurveda offers

Curcumin improved blood sugar markers, and periods a little, in small trials. Most Ayurveda studies of PCOS are single case reports.

Psoriasis and eczema: what Ayurveda offers

The evidence is thin. Curcumin has some trial support in psoriasis, we found no eczema trial, and one Ayurvedic psoriasis medicine contains arsenic.

Type 2 diabetes (sugar): what Ayurveda offers

Some herbs, such as methi and karela, lowered HbA1c a little in trials. Taken with diabetes medicines, they can add to the risk of low sugar.

Underactive thyroid (hypothyroidism): what Ayurveda offers

One small trial found ashwagandha improved mildly raised TSH. No trial we found tested Ayurveda in place of levothyroxine. Do not stop it.

Food

Classical food rules, checked against modern nutrition.

Can Ayurvedic medicines match celecoxib for knee pain?

In a six-month trial of 440 people, two Ayurvedic formulations matched glucosamine and celecoxib for knee pain. Some had raised liver enzymes.

Do Ayurvedic herbs help IBS with diarrhoea?

A small placebo-controlled trial of curry leaf, pomegranate and turmeric found no benefit over placebo for diarrhoea-predominant IBS.

Does ashwagandha change thyroid blood tests?

In one small trial of people with a mildly raised TSH, eight weeks of ashwagandha root extract moved thyroid tests towards normal.

Does ashwagandha hair serum help hair loss?

One 75-day trial found a small gain in hair density with an ashwagandha scalp serum. The extract's maker sponsored the trial.

Does ashwagandha improve sleep?

A 2021 review of five trials found a small improvement in sleep with ashwagandha extract. The effect looked larger in people with insomnia.

Does ashwagandha reduce stress?

One small placebo-controlled trial found ashwagandha root extract lowered stress scores and cortisol over 60 days. Promising, not settled.

Does boswellia (shallaki) help osteoarthritis pain?

A Cochrane review found one enriched boswellia extract eased osteoarthritis pain over 90 days. A review of Ayurvedic trials was less sure.

Does curcumin help indigestion (functional dyspepsia)?

In a 132-person trial, curcumin eased indigestion more than placebo over four weeks. That does not make it equal to omeprazole.

Does karela (bitter melon) help type 2 diabetes?

A 2022 review found karela lowered HbA1c slightly, by 0.3 points, in poorly reported trials. An older Cochrane review found no clear benefit.

Does whole-system Ayurveda help knee pain?

In a trial of 151 people in Germany, 12 weeks of Ayurvedic care eased knee osteoarthritis more than conventional care. Patients knew which they had.
