अवलेह Avaleha or extract. To prepare it, decoctions, after being strained, are again boiled down to the consistence of a thick extract. This extract, when properly made, does not readily dissolve in water, can be drawn out into wires, and will receive impressions of coins on its surface. Extracts are administered with the addition of sugar, decoctions, or powders.
