I have been reading several articles about Lepidium sativum during the last days. Every article mentioned lots of medicinal uses of this herb. Also, little or no increase in mortality among animals was recorded and I was wondering what the limitations are, if there are any, that could have affected the progress of researches on this herb. Also if there is any information about this herb that you think I need to know, I would be grateful if you could introduce it to me!
