Stavesacre is a very poisonous plant that is rarely used in modern herbal medicine[238]. The seed is antispasmodic, cathartic, emetic and vermifuge[4, 44]. The seeds cause a strong salivation if they are chewed and have been used in the treatment of toothache and other painful conditions of the throat and gums[232]. They are so strongly emetic and cathartic, however, that they are rarely used internally[4]. Externally, a decoction is used to treat itchy skin and parasites4]. The seed is very poisonous and should be used with great caution[4]. The plant has been used externally in the treatment of warts, lice and itches[232]. A homeopathic remedy is made from the seeds[232]. This is used in the treatment of a variety of ailments including toothache, injuries and headache[232].

Plant Propagation

Seed - sow March in a cold frame or April outdoors. Keep moist and in a shady position until germination takes place[175]. Seed can also be sown either in a cold frame or in situ as soon as it is ripe in mid to late summer[175], though seedlings from the outdoor sowing can be killed in cold winters[K]. The seed has a limited viability so it should be stored in a sealed container at about 3°c[200]. Temperatures above 15°c inhibit germination[175]. The seed usually germinates in 2 - 9 weeks at 15°c[175].
