Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


Visnaga is an effective muscle relaxant and has been used for centuries to alleviate the excruciating pain of kidney stones[254]. Modern research has confirmed the validity of this traditional use[254]. Visnagin contains khellin, from which particularly safe pharmaceutical drugs for the treatment of asthma have been made[254]. The seeds are diuretic and lithontripic[46]. They contain a fatty oil that includes the substance 'khellin'. This has been shown to be of benefit in the treatment of asthma[238]. Taken internally, the seeds have a strongly antispasmodic action on the smaller bronchial muscles[254], they also dilate the bronchial, urinary and blood vessels without affecting blood pressure[238]. The affect last for about 6 hours and the plant has practically no side effects[254]. The seeds are used in the treatment of asthma, angina, coronary arteriosclerosis and kidney stones[238]. By relaxing the muscles of the urethra, visnaga reduces the pain caused by trapped kidney stones and helps ease the stone down into the bladder[254]. The seeds are harvested in late summer before they have fully ripened and are dried for later use[254].

Cultivation details

Prefers a well-drained soil in a sunny position[238], succeeding in ordinary garden soil. Tolerates a pH in the range 6.8 to 8.3. This species is not fully winter-hardy in the colder areas of Britain, though it should be possible to grow it as a spring-sown annual[238]. This plant is sold as toothpicks in Egyptian markets[46].
