Asra Visruti / S`hon`ita Nirharan`a / Asra Visraavan`a
- The process in which vitiated blood, Vaata, Pitta and Kapha are allowed to come out of the body through Siraa is termed as Raktamokshan`a. It’s is one of the eightS`hastrakarma described by Sus`hruta.
- It’s a procedure in which entrapped Vaayu is drained through Viddha (puncture) in the skin. This also helps to let out entrapped circulation in blood vessels.
Two main types
- S`hastra Rahita i.e. blood letting done with the help of Anus`hastra.
- Oleation and fomentation therapy should be administered locally for Siraavedha S`hringa Karma and Alaabu Karma. It produces anaesthesia and reduces pain during prick. As Dosha are S`haakhaagata (i.e. in Siraa). No internal oleation or fomentation is required as Dosha are not to be brought in Kosht`ha as in Vamana andVirechana.
- Quantity of blood letting should be 540 ml according to Samhitaa. But now a days 250 ml of blood is the maximum quantity accepted all over for a healthy person and 40 to 100 ml for a diseased person (as emergency measure).
- Still if patient develops the signs of Raktakshaya blood letting should be stopped immediately.
- The patient should be advised to consume diet having following properties
o Laghu (easy to digest)
o Agnideepana (stimulating the digestive power)
o Raktavardhaka (facilitating blood formation)
o Na Ati Ushn`a Na Ati S`heeta (should not be very hot or cold in potency)
Chikitsaa Karma (Benefits):
- Raktamokshan`a in the surgical branch of clinical medicine is as important as Basti in internal medicine. It is equally potent and effective in controlling pathology
- The importance of Asravisruti is equally important in chronic diseases as well as acute disorders. The modality being vene puncture.
- The role of Rakta flowing in its normal channels is to facilitate all movements, fill the vessels and provide unfailing perception of touch.
- Siraa always carry all Dosha along with Rakta. Vedanaa indicates deranged or Vikrita Vaayu and this is an ideal indication for Raktamokshan`a.
- Relieves pain and severity of the condition.
- If there is no relief from pain by Snehana and Svedana, Raktamokshan`a should be carried out which should be followed by Agni karma.

- Raktamokshan` should be done in Vaataja Gulma if all other measures indicated for Vaataja Gulma fail.
- Kusht`ha which are stable, hard and rounded should be fomented by Prasthara and Naadi types of Svedana and then rubbed with Kurcha.
- In elevated patches of Kusht`ha fomentation should be done by Pot`t`ali containing meat of aquatic animals.
- If the patches are numb and anaesthetic, absence of perspiration and itching, then they should be rubbed with Kurcha or with steams of Danti, Trivrit, Karanja,Karaveera and Kut`aja, Leaves of Jaati, Arka and Nimba or with sharp instruments or with Samudraphena or dried cow dung.
