The trial base

How much human evidence actually exists

Human clinical trials reviewed per herb. Bar colour shows our verdict — green Proven, orange Promising, grey Limited. A longer bar means more trials exist, not that the herb works better.

Proven

1

Multiple quality RCTs confirm these effects.

Boswellia (Shallaki)

9 RCTs reviewed — the most consistent single-condition evidence base we found

Promising

8

Some clinical evidence exists but more research is needed.

22 RCTs reviewed — stress and sleep signals, with real caveats on trial quality

17 RCTs reviewed — bioavailability decides whether the evidence applies at all

9 RCTs reviewed — cognition changes show up only past the 8-week mark

9 human trials reviewed — gut and dental data hold up, the rest is thin

Amla (Indian Gooseberry)

8 RCTs reviewed — lipid and glucose markers are the real story

Tulsi (Holy Basil)

7 RCTs reviewed — stress and sleep data exist, sample sizes stay small

5 RCTs reviewed — strongest for oral health and psoriasis, patchy elsewhere

5 human trials reviewed — small lactation dataset, PCOS claims largely untested

Limited

2

Insufficient human clinical data available.

6 trials reviewed — popularity far outruns the clinical trial base

Giloy / Guduchi

4 RCTs reviewed — thin evidence, plus a documented liver injury signal
