Polygonatum biflorum
Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.
Enhanced precautions for this plant: The raw rhizome contains irritating compounds (particularly saponins and calcium oxalate) that may cause digestive disturbances or irritation in case of significant ingestion or poorly controlled preparation. The berries of Solomon's Seal are considered toxic and should under no circumstances be consumed. Internal use, pregnancy, breastfeeding, and use in children require prior advice from a healthcare professional, as current data is insufficient. Confusion is possible with other plants with similar berries or rhizomes growing in the same undergrowth; positive identification is essential before any harvesting.
Poultice — Fresh Rhizome
Traditional poultice for bruises
The fresh rhizome is washed, then grated or coarsely crushed to obtain a moist paste. This is applied directly to the bruised area, held in place with a clean cloth, and renewed after a few hours. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
Decoction — Dried Rhizome
Light decoction of dried root
The dried rhizome, cut into small pieces, is gently boiled in water then left to infuse off the heat. This preparation, of traditional use, must be established under the guidance of a professional well-versed in the plant. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
Tincture — Fresh Rhizome
Fresh root tincture
The finely cut fresh rhizome is macerated for several weeks in alcohol of appropriate strength, away from light, then filtered. This concentrated form requires rigorous preparation and specialized advice before any use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
