Medicinal use of Larkspur:

Larkspur formerly had a reputation for its ability to consolidate and heal wounds, whilst the juice from the leaves is considered to be a remedy for piles and an infusion of the flowers and leaves has been used as a remedy for colicky children. However, the whole plant is very poisonous and it should not be used internally without the guidance of an expert. Externally, it can be used as a parasiticide. A tincture of the seed is applied externally to kill lice in the hair.
