Please 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.
Increased precautions for this plant: The entire plant is considered toxic, like other delphinium species, due to diterpene alkaloids similar to those found in aconite. Ingestion may cause severe cardiac and neuromuscular disturbances; it is strongly discouraged in any form, including small amounts. Absolutely contraindicated in pregnant or breastfeeding women, children, and individuals on cardiovascular treatment. No internal or external use should be undertaken without the advice of a qualified healthcare professional; this monograph is presented for historical and informational purposes only.
No recommended traditional preparation — Aerial parts and root

Due to its confirmed toxicity and the lack of reliable documentation on safe traditional uses, no preparation - infusion, decoction, or other - is suggested here.
