Medicinal Uses

Anthelmintic;  Diuretic;  Hypnotic;  Hypotensive;  Parasiticide;  Purgative;  Vasodilator.

Larkspur was at one time used internally in the treatment of a range of diseases, but its only certain action is a violent purgative and nowadays it is only occasionally used in folk medicine[268]. It is of value, however, when used externally, to kill skin parasites[268]. The plant should be used with caution[9, 21], see the notes above on toxicity. The seed is anthelmintic, mildly diuretic, hypnotic, purgative and vasodilator[21]. It has been used internally in the treatment of spasmodic asthma and dropsy[4]. The flowers or the whole plant are mildly diuretic and hypotensive[9]. The expressed juice of the leaves has been considered an effective application to bleeding piles[4]. A conserve made from the flowers has been seen as a good remedy for children when subject to violent purging[4]. The juice of the flowers has also been used as a treatment for colic[4].


Other Uses
Dye;  Ink;  Insecticide;  Parasiticide.

A strong tincture of the fresh seed is used externally to kill lice and nits in the head and pubic hair[4, 61, 74, 268]. It is also effective against aphids and thrips[20]. A good blue ink is obtained from the expressed juice of the petals together with a little alum[4]. It is made from the leaves according to another report[74]. It is also used as a dye[74] and is green when mixed with alum[46, 61].
Cultivation details
An easily grown plant, it prefers a sunny position in a well-drained soil. Plants succeeded when growing in a dry shady position in the hot dry summer of 1989[K]. A very ornamental plant[1]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[54]. Other reports say that it is a good companion for wheat[18, 20]. A good bee plant[74].
