Keeping in view the wide applications of T. terrestris, it is very important to know the inorganic constituents and its possible role in the body. For this purpose the plant was collected from two areas of Mardan and Peshawar, Pakistan. The inorganic constituents including total hardness, total alkalinity, Na⁺, K⁺, Mg²⁺, Cl^-, CaCO₃^2-, SO₄^2- were determined. It is also important to know the differences of the inorganic constituents while the plant is grown in different natural habitats.
