Herbal Terms that you will come across.
After pre-moistening, wrap one part herb (dry weight) in cloth and suspend it in 32 parts of water (by volume) at room temperature, overnight.
Squeeze out the herb into the tea in the morning, and add enough water to bring it back to 32 parts.
Boil 32 parts of water, remove from heat, and steep one part (by weight) of the herb in the water for 20-30 minutes.
Strain, and pour sufficient water through the herb in the strainer to return the volume of tea to 32 parts.
Combine 32 parts of water with one part of herb (by weight), bring slowly to a boil, continue for ten minutes, cool until warm, and strain.
Pour additional water through the herb to return the volume to 32.
A WEAK DECOCTION is the same, but using half as much herb in the same volume of water.
COMMENTS. Except for the weak decoction, the above teas end up with 30 mls having the constituents of a gram of herb. If the dosage recommends 120 mls of Strong Decoction, and you only want a single batch, use 4 grams of herb, or divide a gram of herb into eight equal parts and use one part for the tea. (Approximate only)
DO NOT MAKE MORE THAN A DAY'S WORTH OF TEA AT ONE TIME.
EYEWASH and DOUCHE
Make an isotonic water by adding a slightly rounded teaspoon of salt to a litre of clean water (1/4 teaspoon per cup), and make the tea with this solution as per the recommended strength.
Make a fresh batch every 5-6 hours.
FRESH PLANT TINCTURE
One part by weight of the fresh, chopped herb is steeped for 7-10 days in two parts by volume of alcohol (190 proof or 95% ethanol), and pressed or squeezed out.
There is no reason to blend or shake this maceration; the tincture is formed passively as a result of dehydration.
Ethanol draws out all plant constituents that contain water, leaving only cellulose and dead tissue behind.
DRY PLANT TINCTURE
Maceration. If the Materia Medica calls for a [1:5, 60% alcohol] tincture, it means this: your solvent is 60% alcohol and 40% water (the water is presumed), and one part of herb by weight has been invested in five parts of solvent by volume.
As to the terminology used by herbalists in this regard: The resulting solvent is called the 'Menstruum' and the remainder of the plant material left in the bottom is called the 'Marc'.
