Apamarga Kshara Information, Preparation and Uses

The Kshar prepared from Apamarg is known as Apamarga ksara. It is potash rich alkaline ash of the plant Achyranthes aspera, and is used a single drug or in the preparation of caustic pastes and diuretic medicines.

In Ayurveda, Kshara is the term used for alkaline (basic) ashes of plants. It is derived from the Bhasma of a plant. For Bhasma preparation, first the plant containing more or less alkalis, is dried, made into powder and then burnt till they are completely reduced to ashes. This ash is dissolved in water, strained and again heated to evaporate the water. Dehydrated salty solid obtained by this process is Kshar/Ksara.

The plants used for Kshar preparation include Patala, Kutaj, Arka, Karanj, Adusa, Imli, Punarnava, Apamarga etc. Kshar are used both externally and internally. They have laxative, diuretic and antacid properties. Kshar are rich in potash.

Apamarga Ksara has tikshna (sharp), ushna (hot), picchila (slimy), slaksan (smooth), shulhar (pain relieving) properties.
