HelloPharmacist Scorecard of Neem Plus by Ayush Herbs
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
Neem Plus is a single-ingredient supplement containing neem leaf extract in capsule form. Neem has been used traditionally for oral health and skin conditions.
The product also contains inactive ingredients listed as part of a proprietary blend (these are fillers, binders, and capsule materials that give the supplement its form).
Does it work?
Moderate evidence
The evidence for neem is mixed. It's rated possibly effective for gingivitis (gum inflammation), dental plaque, and lice.
However, the evidence for acne and tungiasis (a parasitic skin infection) is insufficient to establish whether it works. The data we hold doesn't show a strong case for other uses.
How safe is it?
Well-documented data
Neem leaf preparations appear well tolerated in adults when taken by mouth, though thorough safety testing hasn't been completed. Topically, neem is generally well tolerated in both children and adults, though contact dermatitis can occur in sensitive skin.
Rare serious side effects have been reported with oral neem leaf in adults, including heart rhythm problems and kidney effects. Neem oil is not safe to swallow, especially in children — it can cause serious harm.
Neem should be avoided during pregnancy because it may affect fertility and the developing baby. There isn't enough safety data for breastfeeding, so it's best to avoid it while nursing.
If you're pregnant or nursing, talk with your doctor or pharmacist before use.
Meds to double-check
Moderate interaction found
Before taking Neem Plus, double-check with your doctor or pharmacist if you're on antidiabetes drugs (there's a real risk of low blood sugar), immunosuppressants, or any medication your liver breaks down — especially those metabolized through CYP1A2, CYP3A4, CYP2C9, CYP2C8 pathways or P-glycoprotein transport. While these enzyme interactions haven't been seen in humans yet, lab research shows they're theoretically possible.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Neem may be worth considering if you're looking for support with gingivitis or dental plaque and topical use isn't an option. If you take diabetes medications, any immune-suppressing drugs, or medications processed by your liver, you need to check with your doctor or pharmacist first — the interactions could affect how your drugs work.
Pregnant women and those breastfeeding should avoid it.

Neem Plus by Ayush Herbs Drug Interactions
HelloPharmacist Interaction Report
Neem Plus contains neem leaf extract, which has documented interactions with a range of medications.
The most serious concern is with antidiabetes drugs — neem can lower blood sugar levels, which may increase the risk of low blood sugar (hypoglycemia) when combined with diabetes medications, including metformin.
Read the full breakdown — every affected drug type, severity by severity
Neem also theoretically affects how your body processes several major medication classes. It may increase levels of drugs broken down by your liver's CYP1A2, CYP3A4, CYP2C9, and CYP2C8 enzymes, as well as drugs transported by a protein called P-glycoprotein.
While these interactions have been seen in lab studies, they haven't yet been confirmed in humans. Additionally, neem may interfere with immunosuppressant medications, potentially reducing their effectiveness.
If you take any antidiabetes medication, an immunosuppressant, or any prescription drug metabolized by the liver, check your exact medications using the interaction tool on this page before starting neem. Altogether, these interactions span 1,014 individual medications.
