Dosage must be validated with a healthcare professional or a recognized pharmacopoeia before use.

Compress — Leaves

Fresh leaf juice

Fresh leaves are crushed to extract the juice, applied directly to the skin using a clean cloth. This traditional practice aims at cleansing superficial wounds and does not replace appropriate care. Dosage must be validated with a healthcare professional or a recognized pharmacopoeia before use.
