3.4.1 Substitution of the Species Belonging to the Same Family
Plant species belonging to the same plant family have also been observed in the substitution process as a substitution for the
original plant species. This type of substitution is done usually with plants from the same family. Datura metel and Datura
stramonium
can be considered here. The chemical constituents are alkaloids—scopolamine, atropine, hyoscyamine, and hyo-
scine, among others. The alkaloids are found to be bronchodilators, relaxants, and inhibitors of the emissions from the mu-
cous membrane. The alcoholic concentrate of D. metel shows anthelmintic effects. The alkaloids introduced in both species
are well-demonstrated bronchodilators. They likewise hinder the emissions of the mucous membrane of the respiratory tract.
Both D. metel and D. stramonium are beneficial for maladies of the respiratory tract, as they are demonstrated anthelmintics.
