The short answer
The evidence is mixed. In an eight-week trial in Iran, 92 people whose blood pressure stayed high on their usual medicines were randomised to amla capsules or a placebo, and 81 finished. Systolic pressure fell 15.6% with amla and 6.3% with placebo. A larger 12-week trial at JIPMER, Puducherry, found that an amla extract added nothing to the routine medicines of 150 people with high blood pressure.
Both trials said amla was well tolerated, but they were short, and they tested capsules, not fresh amla, juice or powder. If you take a blood pressure medicine and want to add amla capsules, tell your prescribing doctor, and ask whether you should check your blood pressure at home for a while.
Common Indian packs include Telma (telmisartan), Amlong (amlodipine), Cardace (ramipril) and Met XL (metoprolol).
At a glance
| What was seen | How it may work | Direction | Evidence |
|---|---|---|---|
| Extra fall in blood pressure on top of usual medicines[1] | Not established | Blood pressure may fall further than with the medicine alone | RCT |
| No extra fall in blood pressure[2] | Not established | No added effect on the medicine | RCT |
No listing is not a clearance. A missing interaction here never means a combination is safe.
The evidence, study by study
Trial in uncontrolled hypertension, Iran, 2020 RCT
Ninety-two people whose blood pressure stayed high despite their usual medicines added amla capsules (500 mg three times a day) or a placebo for eight weeks. Eighty-one finished. Systolic pressure fell 15.6% with amla against 6.3% with placebo, and diastolic pressure 12.3% against 3.9%. No side effects were reported. Pressure was measured only in the clinic, and the authors could not confirm how regularly people took their usual tablets.[1]
Trial in essential hypertension, Puducherry, 2021 RCT
At JIPMER, 150 people with high blood pressure took capsules of an aqueous amla extract (500 mg twice a day) or a placebo alongside their routine medicines for 12 weeks. Amla gave no additional fall in systolic or diastolic pressure, and it did not change cholesterol, HbA1c or arterial stiffness. The authors found it well tolerated. The product, dose and patients differed from the Iranian trial.[2]
What your doctor may watch for
- Blood pressure readings, at home or in the clinic. In the trial that found an effect, pressure was checked every two weeks.[1]
- Dizziness or light-headedness, especially on standing up, which can be a sign that blood pressure has gone too low.
What to tell your prescribing doctor
You can read this out, or show them this page:
“I am taking, or planning to take, amla (fruit, juice or capsules, and how much) along with my blood pressure medicine. One trial found amla lowered blood pressure further in people already on treatment, and another found no extra effect. Should I check my blood pressure at home for a while?”

Amla and metformin
Amla lowered blood sugar further alongside metformin in one small rat study. Nobody has tested the two together in people.
InteractionAmla and blood thinners
Amla extract slowed platelet clumping in small human studies, alone and with aspirin or clopidogrel. Warfarin has not been tested.
InteractionArjuna and blood pressure medicines
Arjuna capsules lowered blood pressure further in people taking telmisartan, in one small 28-day trial. Other BP drugs are untested.
InteractionAshwagandha and blood pressure medicines
We found no study of ashwagandha with a named BP medicine. A US health agency lists BP drugs among those it might interact with.
