It can be dried, ground into a powder and sprinkled onto wounds etc[213]. It is taken internally in the treatment of diarrhoea, dysentery and gastric ulcers[238]. It should be used with some caution since excess irritates the stomach and can cause kidney and liver failure[238]. The root is harvested in the autumn and is dried for use in decoctions or as a powder[238].

Propagation

Seed - sow early spring in a warm greenhouse and only just cover the seed. Germination is usually fairly rapid. Prick out the seedlings when they are large enough to handle and plant them out into their permanent positions in late spring or early summer. The seed can also be sown in the middle of spring in an outdoor seedbed and planted out in early summer. Alternatively, you can sow the seed in an outdoor seedbed in the middle of summer for planting out in the following spring. Division in March or October[1, 111]. It is best to divide the plants in August or early September, making sure that the woody roots are planted quite deeply with only the crown of foliage above the ground[233].
