Enhanced precautions for this plant: Plant rich in berberine: not recommended for pregnant or breastfeeding women due to reported risks to pregnancy and the infant. Do not use in infants and young children without medical advice, as cases of increased sensitivity to berberine have been documented. Possible interactions with certain medications (anticoagulants, metabolic treatments): consult a healthcare professional before any use. Prolonged or high-dose use not recommended without supervision, as the plant is classified among active substances requiring caution.

Decoction — Dried Rhizome

Traditional root decoction

The dried rhizome, cut into small pieces, is gently boiled in water for about fifteen minutes, according to the classical practices of East Asian pharmacopoeias. This preparation, very bitter, was generally consumed in small quantities and never for prolonged periods. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Powder — Dried Rhizome

Rhizome powder in compound formula

The dried rhizome was ground into fine powder and then incorporated into compound preparations with other plants, following recipes passed down by traditional herbalists. This concentrated form requires precise dosing, reserved for an experienced practitioner. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Compress — Dried Rhizome

External wash and compress

A cooled and filtered decoction was traditionally used to soak a compress applied to the skin or to rinse tired eyes. This external use was considered gentler than internal use, but still requires caution in case of sensitive skin. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
