many poisonous plants, such as Belladonna (Atropa belladonna), 

 Stramoniiun {Datura stramonium)^ (D. tatula), and (D. metel), 

 Henbane (Hyoscyamus niger). and many others. In fact all of the 

 species, unless well known to be harmless, should be used with 

 caution. Of the species growing in a wild state in Natal, one, S. 

 capense, has been used by the natives for curdling milk, and some 

 have been used medicinally ; but great care should be exercised in 

 their use. Withania somnifera has been used in Xatal medicinally 

 by Europeans, it is said with some amount of success ; but it is a 

 doubtfully indigenous plant.
