Pregnancy
Use CautionThis herb is processed through the liver, which is already working harder during pregnancy — generally used cautiously and not at high/concentrated doses without guidance. This is a general, mechanism-based caution, not herb-specific research.
Breastfeeding

Children
Use CautionA child's liver is still developing its full drug/herb-processing capacity — these herbs are generally used cautiously and at reduced, age-appropriate doses.
Contraindications

- Diabetes medications — may enhance hypoglycaemic effect; monitor blood glucose closely
Warnings

⚠️ Liver Health
Some herbs used for liver conditions can be hepatotoxic at high doses. Have liver function monitored if using long-term.

Drug & herb interactions
May affect drug absorption
Watch for: Any oral medication taken around the same time
High-fiber or mucilage-rich herbs can slow or reduce how much of another oral drug is absorbed — space doses a couple of hours apart.
Processed by the liver
Watch for: Any medication that is also processed by liver enzymes (ask your pharmacist — this includes many common prescriptions)
Can alter how quickly the body clears certain medications, raising or lowering their effective dose.
May have a diuretic effect
Watch for: Diuretic medications and lithium
Additive fluid loss can affect electrolyte balance and change how the body clears lithium.
May affect blood sugar
Watch for: Insulin and oral diabetes medications (metformin, sulfonylureas)
Additive blood-sugar-lowering effects can risk hypoglycemia — monitor glucose closely.
