Regular or high-dose use is not recommended; consult a healthcare professional before any use.

Infusion — Dried leaves

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

Smoke (dried leaves) — Dried leaves

Ritual fumigation

The dried and crumbled leaves were sometimes smoked alone or mixed with traditional tobacco during vigils, a practice reserved for supervised ritual use rather than domestic use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
