Antispasmodic Blood purifier Demulcent Expectorant Parasiticide Sedative Stomachic
The leaves and flowering tops are antiphlogistic, antispasmodic, balsamic, demulcent, expectorant, sedative, stomachic and a vascular tonic[4, 7, 21, 46, 61, 207, 213]. Blood purifier[4]. The plant is applied externally as a compress on inflamed or irritated areas of the skin[7, 257]. Used internally, it slows down the heartbeat and reduces the stimulation of the nerve endings in the air passages that causes coughing - it is therefore extremely effective as a calming agent in the treatment of asthma[7]. The fluid extract is prepared by placing the freshly gathered leaves and flowers in a small quantity of simmering water for about 15 minutes[213]. The plant is used to treat people affected by poison-ivy[213].

Cultivation details
Succeeds in any well-drained soil in full sun[200]. Does well on dry sandy banks and in poor soils[200]. Plants tend to concentrate selenium in the leaves and stems, this is especially noticeable on soils that are relatively rich in that element[21]. Some authorities class this species as a synonym of G. camporum.
