Seed . . . . ? This descriptionis principally taken from Mr. Don's account ;what regards the fruithas however been drawn up from an examination of a couple ofmericarps, for which I am indebted to that gentleman. The stem andfruits yield a great abundance of the fetid gum resin Ammoniacum ;its action is similar to that of Asafcetida. It is chiefly employed as adiscutient and expectorant.47
