Herbier des Anciens — Detailed Monograph

Gelsemium sempervirens

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: Highly toxic plant: all parts, especially the root, contain alkaloids (gelsemine) that can cause severe neurological and respiratory disorders, even in small quantities. Raw use is strongly discouraged without supervision by a qualified professional; never prepare a decoction or tincture yourself from fresh plant material. Contraindicated in pregnant or breastfeeding women, children, and individuals with pre-existing cardiac or respiratory conditions. Do not combine with sedatives, nervous system depressants, or other alkaloid-containing plants without medical advice, due to the risk of severe interactions.

Mother tincture (restricted use) — Dried root

Traditional highly diluted tincture

Historically prepared by macerating dried root in alcohol, this tincture was only used by practitioners in extreme dilutions, in counted drops. Its preparation and use should never be improvised at home. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Homeopathic granules — Root (raw material for potentization)

Homeopathic preparation

The Gelsemium sempervirens source, obtained through dilution and potentization in pharmaceutical laboratories, is the only commonly accessible form today. It should be selected according to the recommendations of a pharmacist or homeopathic practitioner. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Obtaining the plant

This toxic plant has no place in amateur foraging; it grows naturally in the forests and moist edges of the southeastern United States. In France, it is only available as homeopathic preparations in pharmacies.

Harvest season

When to harvest it

In its native range, flowering occurs in spring, but root harvest, reserved exclusively for trained professionals, is traditionally practiced in autumn.
