Features of horn used

Characteristics of horn used for blood letting :
It is conical, hollow and bent inwards at distal end.
Length – 18 angula (36 cm)
Circumference in the middle -12 angula (24 cm)
Diameter of orifice at base – 3 angula (6 cm)
Diameter of orifice at tip – 1/2 – 3/4 cm (size of mustard)

A slender and straight cow’s horn is obtained, cleaned well both inside and outside, this hollow piece is cut with a saw at both its ends, so as to make wider opening at its base (6 cm) and another small opening at its front tip (1/2 – 3/4 cm), which resembles the nipple and covered with the layer of thin leather.

Care is taken to make the edges of both orifices even, so as not to injure the skin of both patient and physician during its use. Horn prepared thus can be preserved for many years.

Shringa application

Application of Shinga in blood letting therapy :
Clean the affected area with anti septic solution.
Small incisions are made over the area, then the wider orifice of the horn is placed over the site and held firmly by the hand. Blood from the other orifice is sucked out by force through the mouth.

Fluids like blood, pus etc comes out from the site, as the horn is long enough and fluid coming out is little in quantity, it is placed at the edges of the horn. Sucking may have to be done more than once to draw out the vitiated blood.
