Garlic has been used worldwide as a folk medicine to cure a wide range of diseases. Although Allium sativum is the species commonly used, several other Allium species have been used as a substitute for common garlic, especially in the past. This work compares the extracts from bulbs of common garlic with those of other Allium species. TLC analysis was used to compare the sulphur compounds in A. sativum, A. subhirsutum, A. pendulinum, A. roseum, and A. triquetrum. Results have showed that the use of the above mentioned wild Allium species is not without scientific support.
