Avoid during pregnancy or breastfeeding, as well as in young children. Do not ingest the plant without advice from an herbalist or physician experienced in its use.

Direct Latex Application — Stem

A freshly cut stem releases a milky latex, applied in very small quantities and locally using a stick or cotton swab, avoiding contact with sensitive areas. This traditional practice requires caution and moderation. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
