Contraindications

• Children under 12: Use fruit pulp paste externally only.
• Peptic Ulcer Disease: Tannins in the herb might irritate the mucosal lining.
• Anticoagulant Therapy: Tannins can alter drug bioavailability, potentially raising bleeding risk. Consult a doctor if you are on anticoagulants.
• Liver Disease: Start with a minimal dose (e.g., 1g bark powder) and monitor liver enzymes. Overuse of high-concentration embelin extracts (≥500mg daily) without monitoring may stress liver enzymes.
• Gastrointestinal Upset: High doses of tannins (more than 10g bark) may lead to nausea or constipation.
• Allergic Dermatitis: Rare contact sensitivity to fruit pulp compounds is possible; perform a patch test before topical use.
• Pitta Imbalances: Use with caution in individuals with Pitta imbalances, as excessive consumption may aggravate Pitta-related conditions.

Side effects

• Allergic Dermatitis: Rare contact sensitivity to fruit pulp compounds. Perform a patch test before topical use.
• Hepatotoxicity Risk: Overuse of high-concentration embelin extracts without monitoring may stress liver enzymes.
• May aggravate Pitta: Overconsumption can aggravate Pitta dosha, leading to symptoms such as acidity, ulcers, heartburn, or skin irritation.
• Dehydration: Due to its drying properties, excessive use of Tinduk can lead to dehydration or exacerbate Vata imbalances.
• Digestive Disturbances: Can cause digestive issues if not used properly.

Interactions

• Anticoagulants: Tannins can alter anticoagulant absorption. People on warfarin should be cautious.
