t This plant was formerly in repute as a medicine; but it does not seem to possess any 
remarkable qualities. It is asserted, that the leaves strewed in granaries destroy the Corn 
Weevil. It contains, I have been informed, a considerable quantity of nitre, and that in 
making an extract from it, the mass has taken fire. The Nitraria also contains the same 
salt, and is said not to flourish unless nitre be mixed with the soil in which it grows. Dr. 
Stokes.
