Medicinal Uses

Anthelmintic Narcotic The whole plant, but especially the root, is anthelmintic and narcotic[4, 21, 46]. A safe and effective anthelmintic when used in the proper dosage, it is especially effective with tapeworms and roundworm[4]. Its use should always be followed by a saline aperient such as magnesium sulphate otherwise unpleasant side effects will follow[4]. Another report says that it can be used with other herbs such as Foeniculum vulgare or Cassia senna[254]. These will ensure that the root is expelled along with the worms since the root is potentially toxic if it is absorbed through the gut[254]. The root is best used when fresh but can be harvested in the autumn then dried and stored[213]. It should not be stored for longer than 2 years[213]. Use with caution and only under professional supervision[21, 254]. The plant contains the alkaloid spigiline,which is largely responsible for the medicinal action but side effects of an overdose can include increased heart action, vertigo, convulsions and possibly death[222, 274].
