Can You Take Green Tea Extract (EGCG) and Wormwood Together?

Use extra care with this pair

The short answer

Both EGCG and Wormwood have hepatotoxic effects. High-dose EGCG causes oxidative liver injury, while thujone in Wormwood is directly hepatotoxic.

How to arrange timing

Avoid combining. Keep EGCG at moderate doses if wormwood is used for antiparasitic or digestive purposes.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
