HelloPharmacist Scorecard of Kalmegh Powder by Banyan Botanicals

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Kalmegh Powder is a single-ingredient supplement containing andrographis, an herb traditionally used in Ayurvedic medicine. The powder form lets you mix it into water or other liquids.

There are no inactive ingredients or fillers listed for this product.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: immune support and respiratory health.
  • We looked for evidence on: Acute bronchitis, Influenza, Rhinosinusitis, Tonsillopharyngitis, Upper respiratory tract infection (URTI), Common cold — and 3 related terms.
  • The strongest evidence on file: Andrographis is rated "Possibly Effective" for Tonsillopharyngitis (Natural Medicines).
  • Also on file: Andrographis is rated "Insufficient Reliable Evidence To Rate" for Acute bronchitis, Upper respiratory tract infection (URTI), Influenza, Rhinosinusitis, and more.

Andrographis has possibly effective evidence for three conditions: ulcerative colitis (an inflammatory bowel disease), tonsillopharyngitis (sore throat and tonsil inflammation), and osteoarthritis (joint wear-and-tear). For familial Mediterranean fever, the evidence isn't established enough to rate it.

If you're considering this supplement for a specific condition, talk with your pharmacist about what the research actually shows for your situation.

The evidence, ingredient by ingredient Andrographis

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Andrographis is generally well tolerated in the short term, but long-term safety and product quality aren't well established, so caution is warranted if you're thinking of using it for weeks or months. The most common side effects are stomach discomfort, nausea, diarrhea, headache, fatigue, dizziness, altered taste, rash, and itching — these happen especially at higher doses (5–10 mg/kg of andrographolide or more) or beyond 14 days of use.

Rare serious reactions include severe allergic responses, including anaphylaxis. Skin reactions — including Stevens-Johnson syndrome, a severe skin condition — have been reported.

Andrographis is not safe in pregnancy because of theoretical and animal concerns about reproductive effects. There isn't enough safety data to breastfeed while taking it, so avoid use during lactation.

Side effects, ingredient by ingredient Andrographis

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Andrographis.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 413 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take Kalmegh Powder, check with your pharmacist if you're on blood pressure medications (antihypertensives) or blood thinners (anticoagulants or antiplatelet drugs) — both carry Moderate interaction risk. Also flag immunosuppressants, etoricoxib (Arcoxia), celecoxib (Celebrex), or glipizide (Glucotrol).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Kalmegh Powder may help with sore throat, inflammatory bowel disease, or osteoarthritis, but check with your pharmacist first if you take blood pressure meds, blood thinners, or immunosuppressants. It's best used short-term and at standard doses.

Avoid it in pregnancy and while breastfeeding.

Andrographis6 drug types · 413 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, andrographis might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal and laboratory studies suggest that andrographis has antiplatelet effects.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, andrographis might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that andrographis has hypotensive effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, andrographis might interfere with the effects of immunosuppressive drugs.
Laboratory research suggests that andrographolide has immunostimulant activity.

Likelihood Possible Evidence D
Celecoxib (Celebrex)

Theoretically, andrographis extract might increase the maximum concentration and time to peak concentration of celecoxib. The clinical significance of these changes is unclear.
Animal research suggests that andrographis extract taken orally increases the maximum concentration and time to peak concentration of celecoxib but does not appear to impact the area under the curve.

Likelihood Possible Evidence D
Etoricoxib (Arcoxia)

Theoretically, andrographis might decrease the absorption of etoricoxib, although the clinical significance is unclear.
Animal research shows that andrographis extract, or the constituent andrographolide, taken orally with etoricoxib decreases the bioavailability of etoricoxib. However, this reduced bioavailability is not correlated with a reduction in the anti-inflammatory effects of etoricoxib in arthritic mice models. The clinical significance of this interaction is unclear.

Likelihood Possible Evidence D
Glipizide (Glucotrol)

Theoretically, andrographis extract might increase the maximum concentration and area under the curve of glipizide; however, opposite effects are seen with the constituent, andrographolide. The clinical significance of this interaction is unclear.
Animal research suggests that andrographis extract taken orally with glipizide in diabetes-induced rats increases the maximum concentration and area under the curve of glipizide. However, the opposite effect is seen with the constituent, andrographolide, in which the maximum concentration and area under the curve are decreased when taken with glipizide.

Kalmegh Powder by Banyan Botanicals: Common Questions

Does Kalmegh Powder by Banyan Botanicals interact with any medications?
Yes. Based on its ingredients, Kalmegh Powder has a known interaction with 413 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Kalmegh Powder contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Kalmegh Powder if I'm pregnant?
No. The safety data advises against it because of theoretical and animal-study concerns about effects on the baby. Talk with your pharmacist or doctor about what to do instead.
Is Kalmegh safe to breastfeed on?
There isn't enough safety information, so it's best to avoid it while breastfeeding. Ask your pharmacist about safer options.
What are the most common side effects?
Stomach discomfort, nausea, diarrhea, headache, fatigue, dizziness, and rash are the most common, especially at higher doses or if you use it longer than about 2 weeks. Rare serious reactions include severe allergic responses.
Does andrographis actually work for sore throat?
Yes — there's possibly effective evidence that it helps with tonsillopharyngitis (sore throat and tonsil inflammation). The evidence is also possibly effective for ulcerative colitis and osteoarthritis.
Can I take this long-term?
The safety data focuses on short-term use, and long-term safety isn't well established. It's safest to use it for 2 weeks or less. Talk with your pharmacist if you're thinking of using it longer.
What's in this powder besides andrographis?
Just andrographis — there are no fillers or other inactive ingredients.
