The Kshara is one dosage form used in the Ayurveda, Indian medicine. It is produced from the ash of plant and shows alkalinity. With the corrosive action, the Kshara Sutra, a thread covered with the Kshara made from the whole plant of Achyranthes aspera L. of the family Amalanthaceae, is used for the effective surgical operation of an anal fistula. In the past, there have been various theories about the manufacturing method of Kshara. Physicochemical studies on the properties of the Kshara made from A. aspera produced in Sri Lanka clarified that it was a powder derived from the sediment taken from suspension of the half incinerated ash of the plant. Moreover, the equivalent powder could be made from other Achyranthes plants such as A. bidentata BLUME var. tomentosa (HONDA) HARA growing wild in Japan.
