Safety first. Supplements can cause side effects and interact with medicines. Read mushroom safety and interactions before you use any mushroom product.
This is not a dosage chart. Each row is what an EU herbal monograph describes for an authorised traditional product, for a specific herb, use, age group and time limit. It is regulatory information about those products, not a recommendation for you and not a way to compare herbs. Different herbs and preparations are not equivalent, and an amount for one cannot be applied to another. For most adults the key points are the time limits and the cautions.

How to read this table
- These amounts are for authorised traditional herbal products, where the product is made to a standard. A bag from a shop may contain a different amount of herb. Check the label.
- Time limits matter more than they look: fennel (2 weeks), nettle (2 to 4 weeks) and several others come with a "see a doctor if it lasts" rule.
- The monographs also list amounts for children for some herbs. We do not reproduce them, and we do not recommend giving herbal drinks to babies or children without a pediatrician.
- "Traditional use" means long-standing use, not proof from clinical trials. [1]
- Ginger's EU monograph describes powdered rhizome and tinctures, not tea, so it is not in the table. [11]
