pilular

Distil off most of the spirit, and evaporate residue in a water bath to pilular consistence.

Mix the two extracts, and evaporate at a temperature not exceeding 160 to a pilular consistence.

After 24 hours filter the liquor, and evaporate to a pilular consistence.

To the last add a little powdered Castile soap, when it begins to thicken, and evaporate to a pilular consistence.

It is kept in two states—one having the consistence of thick treacle; the other, that of a pilular extract.
