It is recommended in the form of ointment for external use (1: 9 parts of plant's extract and wax ointment). Warning: The use of herb preparations is not recommended without seeking advice from your physician or pharmacist. The substances they contain may interact with the subscribed drugs that the patient already takes, thus eliminating their therapeutic efficacy or inducing toxicity. They may also burden further weakened vital functions of the body thus exposing the patient to increased morbidity and life threatened conditions. |
Toxicity- Adverse Effects | The swallowing of plant's extract (mainly from the leaves and the shoots) may cause salivation, drowsiness, muscle pain, renal failure, rhabdomyolysis, tachycardia followed by bradycardia, loss of speech, muscle paralysis, loss of consciousness, paralysis of the respiratory muscles, neurotoxicity and death. It is worth mentioning that the Athenian philosopher Socrates is killed from conium. |
