FAQ
Frequently Asked Questions
Etymologically, both 'delphinine' and 'dolphin' derive from the Greek 'delphis' (dolphin), due to the shape of the larkspur flower bud resembling a dolphin. However, in modern usage, 'delphinine' refers exclusively to the plant toxin, not the marine mammal.
No. Delphinine is a potent poison, not a modern medicinal compound. Its historical use in medicine has been abandoned due to its extreme toxicity and the availability of safer alternatives.
No, it is an extremely rare and specialised term. Most native English speakers would not recognise it unless they have a background in botany, toxicology, or historical pharmacology.
This is a medical emergency. Seek immediate professional medical help. Do not induce vomiting unless instructed by a poison control centre or doctor.
