Infusions
Infusions are typically used for delicate herbs, leaves and fresh tender plants. Preparing an infusion is much like making a cup of tea. Water is brought just to a boil and then poured over an herb (or combination of herbs), it is covered and allowed to sit/steep for 10-15 minutes or so. It can be prepared in the drinking cup (by just pouring the heated water over the herb in the cup) or by dropping the herb into the pot which the water was heated in. Empty gauze tea-bags are even available at some herb stores which can be filled with herbs and then sealed with a iron. If an infusion is prepared in the heating pan/pot, it's best to use a ceramic pot with a lid (avoid metal pots). Stirring it a few times while steeping (especially with cut herbs) is helpful. Keeping the infusion covered while steeping is generally recommended as well (place a saucer on top of the cup, or a lid on top of the pot). The ratio of herb to water can vary depending on the remedy, the plant, and whether cut herb or powdered herb is used. Generally using 1 teaspoon of powdered herb or 2 teaspoons of more bulky cut herb in a 6-8 ounce cup of water is sufficient. If using a powdered herb; stir once halfway through the seeping time and let the powder settle to the bottom of the cup, then drink the infusion off the top (leaving the sediment in the bottom of the cup). If using a cut herb, strain the infusion with a tea-strainer after seeping. Infusions are best prepared as needed and taken the same day it was prepared and can be taken hot, warm, or cold. Standard dosages of infusions are generally one teacup (6-8 ounces), two or three times daily. The entire day's dosage can be prepared in the morning (2-3 cups at one time), and the remainder refrigerated until ready to use. The exceptions are the more aromatic plants with active essential oils. These are best prepared in single dosages (by the cupful) as needed and taken immediately (and while still hot/warm).

Decoctions
Decoctions are usually the method of choice when working with tougher and more fibrous plants, barks and roots (and which have water soluble chemicals). Instead of just steeping it in hot water, the plant material is boiled for a longer period of time to soften the harder woody material and release its active constituents. To prepare a decoction, select a ceramic pot with a snug fitting lid. Measure the amount of herb needed (usually the same ratio of 1 teaspoon powdered herb or 2 teaspoons of cut herb per 8 ounces of water) into the pot and add the proper amount of cold water depending on how many cups of the decoction you wish to prepare. Turn on the heat to medium high and bring to a roiling boil. Place the lid on the pot and reduce the heat to medium or medium-low so that the mixture stays at a good simmer. Simmer it covered for 20 minutes. If you can see steam escaping or smell the aroma of the herb, your lid is not tight enough and valuable essential oils are escaping. After 20 minutes, remove from heat and cool slightly. If using cut herbs, strain the mixture through a tea strainer into a teacup. When straining, make sure to press on the cut herb pieces in the strainer to get as much liquid/decoction out of the herb pieces as possible. If using powdered herb, allow the powder to settle to the bottom of the pot and then pour off the decoction from the top into a teacup (any sediment missed will settle to the bottom of the teacup). Standard dosages for decoction are generally one-half to one cup, two or three times daily. Again, the entire day's dosage can be prepared in the morning (2-3 cups at one time), and the remainder refrigerated until ready to use later in the day.

Strong Decoctions
Depending on the type of plant material used, strong decoctions are prepared in two general ways. The first involves boiling the mixture longer. This is usually indicated when working with larger woody pieces of bark. Longer boiling time, up to 2 hours or more, is sometimes necessary to break down, soften, and extract the larger pieces. Alternatively, when smaller woody pieces are used yet a stronger remedy is wanted, the decoction is prepared as above (boiling 20 minutes), then it is allowed to sit/soak overnight before straining out the herb. When straining, again, make sure to press on the cut herb pieces in the strainer to get as much moisture/decoction out of the herb pieces.

Tinctures
A tincture is an alcohol and water extract which is used when plants have active chemicals that are not very soluble in water, and/or when a larger quantity is prepared for convenience and wanted for longer term storage. Many properly prepared plant tinctures can last several years or more without losing potency. The percentage of alcohol usually helps determine its shelf-life: the more alcohol used, the longer the shelf life. Sometimes the percentage of alcohol and water is unique to the herbs that are used as some active ingredients are more soluble in alcohol and others more soluble in water. The type of alcohol can vary. . . from vodka, rum, or 90 to 180 proof grain alcohol (sold as "everclear" in liquor stores and sometimes cheaper than vodka). Vodka is fine, but remember if it says 80 proof; it is 40% alcohol and the rest is water. In the Amazon, a sugar-cane alcohol resembling rum and called aguardiente is often used to prepare plant tinctures and it is 40 to 50% alchohol (or 80 to 90 proof). To prepare a tincture with a shelf-life of at least one year, plan on using a minimum of 40% alcohol (so you can extract an herb in a bottle of 80 proof vodka or rum without adding any water). Use a clean glass bottle or jar with tight fitting lid or cork. Use a dark colored bottle (like a recycled green/amber wine bottle) or plan on storing the bottle out of the sunlight. When working with dried plants, use two ounces of plant material (cut or powder) for every 8 ounces (1 cup) of liquid. Since many cut herbs can be bulky, measure the amount of cut herb by weight and not volume (ie; most cooks would tell you 2 tablespoons of butter is 1 ounce... however a lightweight bulky leaf is not as heavy as butter in the same volume or by the tablespoon). A "standard 4:1 tincture" usually means 1 part herb to 4 parts liquid (or as above, 1 ounce herb to 4 ounces of liquid). To prepare approximately 1 cup of tincture (some of the liquid will be absorbed by the dry plant material) place 2 ounces of the herb (cut up or powdered) into your clean glass container. Pour ½ cup (4 ounces) of distilled water and ½ cup (4 ounces) of 180 proof alcohol into the container (or just use 1 cup of straight 80 proof vodka and no water). Seal the container and store at room temperature away from direct sunlight. Shake the bottle/jar at least once daily while allowing it to soak/extract for at least two weeks (larger woody cut herb pieces may need to soak for 4 weeks). At the end of two weeks, filter the tincture through a strainer to remove the plant parts (pressing hard on the plant material to get as much liquid out as possible) and pour into a fresh clean glass container and seal. Some like to pour it through a cheese cloth and then use the cheese cloth to more easily wring out the liquid from the plant material. If using a powdered plant for the tincture, stop shaking for three days and the powder will settle to the bottom. Pour the tincture off the top through a piece of cheesecloth to filter it.

Since this method uses a higher ratio of plant to liquid and helps concentrate the chemicals through the use of alcohol, dosages needed for tinctures are usually much less than infusions and decoctions. Average dosages for tinctures are about 1-2 milliliters (about 30 to 60 drops) two to three times daily. The tincture can be placed directly in the mouth for immediate absorption, or placed in a small amount of water or juice. If you dislike the alcohol content (or want to give the remedy to a child), place the dosage in about 1-2 ounces of very hot water and most of the alcohol will be evaporated in the hot water in a minute or two. (Let cool before taking). Store the tincture at room temperature and away from direct sunlight.

Macerations
This method of preparation is certainly the easiest. The fresh or dried plant material is simply covered in cool water and soaked overnight. The herb is strained out and the liquid is taken. Normally this is used for very tender plants and/or fresh plants, or those with delicate chemicals that might be harmed by heating or which might be degraded in strong alcohol. This is also the easiest to adapt to western methods, since tablets or capsules can be used instead. Alternatively, just stir the ground plant powder into juice, water or smoothies and drink.
