Dioscorea communis

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: Toxic plant when taken internally: ingestion of the red berries and tuber can cause severe digestive disturbances and is not recommended for traditional domestic use. External use only, and on healthy, unbroken skin; prolonged contact or use on fragile skin may cause irritation, redness or even burns. To be avoided in pregnant or breastfeeding women, as well as in children, due to lack of data and the known toxicity of the plant. Any application, even external, should be brief and discontinued in case of skin reaction; the advice of a healthcare professional or qualified herbalist is strongly recommended before any use.

Poultice — Fresh tuber

Grated tuber poultice

The fresh tuber was peeled then finely grated to obtain a paste, applied directly to the bruised area using a compress. The preparation was left in place for a limited time, while monitoring for skin reaction. Dosage to be validated with a healthcare professional or recognized pharmacopoeia before use.

Friction — Rhizome

Rhizome friction on painful areas

Thin slices of fresh rhizome were gently rubbed on the skin at joint level, in a short-duration folk practice. This method, due to its irritating potential, requires prior professional advice. Dosage to be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Obtaining the plant

Black bryony grows spontaneously in hedgerows, woodland edges and thickets of Europe; it is virtually unavailable in commercial herbalist shops due to its toxicity, and wild harvesting requires rigorous botanical identification.

Harvest season

When to harvest it

The tuber is traditionally harvested in autumn or winter, when the aerial part has withered, taking care to properly identify the plant to avoid any confusion with other roots.
