Fumigation — Foliage (twigs and scales)

Dried foliage fumigation

A few sprigs of dried foliage are placed on charcoal or briefly burned in open air, according to traditional purification practices. Always practice in a well-ventilated area and away from flammable materials. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Inhalation — Fresh foliage

Vapor inhalation

Crushed fresh foliage is placed in a bowl of hot, not boiling, water to release its aromatic compounds through vapor inhalation. A professional should be consulted before any regular use, especially in case of respiratory disorders. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Infused oil — Foliage and tender bark

Oil macerate for external use

Chopped foliage is left to macerate for several weeks in a neutral vegetable oil, away from light, before filtering. This preparation, for traditional external use only, requires professional advice before application, especially on sensitive skin. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
