Contraindications

• Generally well-tolerated when used in recommended doses.
• Excessive tannins can cause nausea or mild constipation.
• Rare allergic dermatitis has been reported in latex-sensitive individuals due to cross-reactivity with plant proteins. Perform a patch test before topical use.
• Avoid during the first trimester due to theoretical uterine stimulation. Low-dose decoctions may be safe under supervision.
• Use cautiously with anticoagulants like warfarin, as quercetin may increase the risk of bleeding.
• People with iron-deficiency anemia should avoid overuse, as tannins inhibit non-heme iron absorption.
• Overuse of high-concentration embelin extracts without monitoring may stress liver enzymes.

Side effects

• Excessive tannins can lead to nausea or mild constipation.
• Rare allergic dermatitis has been reported in latex-sensitive individuals due to cross-reactivity with plant proteins.
• High tannin doses (more than 10g bark) may lead to nausea or constipation.
• Rare contact sensitivity to fruit pulp compounds; a patch test is recommended before topical use.
• Overuse of high-concentration embelin extracts (≥500mg daily) without monitoring may stress liver enzymes.

Interactions

• Use cautiously with anticoagulants like warfarin, as quercetin may augment bleeding risk.
• Avoid if you're on warfarin without supervision, as it may potentiate anticoagulants.
• People with iron-deficiency anemia should not overuse Tinduka, since tannins inhibit non-heme iron absorption.
• It is advisable to seek your doctor's advice if you are taking this product along with other western (allopathic / modern) medicines. If both Ayurvedic and allopathic medicines are advised together, then it is best to take Allopathic medicine first, wait for 30 minutes and then take the Ayurvedic medicine.

Clinical evidence

Pilot trials suggest potential benefits of Diospyros melanoxylon (Tinduka) in respiratory health, digestive support, and IBS relief. Tribal decoctions have shown cough reduction, and a powder blend containing tendu leaf reduced abdominal cramps in a pilot trial. A clinical pilot study indicated symptomatic relief in IBS patients. Larger randomized controlled trials are pending.
