Techniques: Decoction
Decoction, or boiling, is employed to extract the mucilaginous or gummy parts of substances, their bitter, astringent or other qualities, and is nothing more than boiling the ingredients in a saucepan with the lid slightly raised. Be sure never to use an iron saucepan for astringent decoctions, such as oak-bark, galls, &c., as they will turn the saucepan black and spoil the decoction. The enamelled saucepans are very useful for decoctions, but an excellent plan is to put the ingredients into a jar and then boil the jar, thus preparing it by a water bath, as it is technically termed; or by using a common pipkin, which answers still better. No decoction should be allowed to boil for more than ten minutes.

Techniques: Infusion
Infusion is one of the most frequent operations required in making up medicines, its object being to extract the aromatic and volatile principles of substances, that would be lost by decoction or digestion; and to extract the soluble from the insoluble parts of bodies. Infusions such as calumba and quassia may be made with cold water, in which case they are weaker, but more pleasant. The general method employed consists in slicing, bruising or rasping the ingredients first, then placing them in a common jug (which should be as globular as possible), and pouring boiling water over them. Cover the jug with a cloth folded six or eight times, but if there be a lid to the jug so much the better. When the infusion has stood the time directed, hold a piece of very coarse linen over the spout, and pour the liquid through it into another jug.

Techniques: Digestion
Digestion resembles maceration, except that the process is assisted by a gentle heat. The ingredients are placed in a flask, such as salad oil is sold in, which should be fitted with a plug of tow or wood, and have a piece of wire twisted round the neck. The flask is held by means of the wire over the flame of a spirit lamp, or else placed in some sand warmed in an old iron saucepan over the fire, care being taken not to place more of the flask below the sand than the portion occupied by the ingredients.

Definition: Astringent
Astringents are medicines which condense and coagulate the tissues,
thereby arresting discharges. When taken into the mouth, they produce the sensation known as puckering. They are used internally and locally. The term styptic is used as a synonym of astringent, but is generally employed to designate those astringents which arrest haemorrhage, or bleeding.
