Tincture : method

The term tincture refers to a preparation with alcohol, vinegar, wine or glycerine. Herbal tinctures are alcoholic or water-alcoholic. Alcool is a better solvent than water for extracting plant constituents. In general, tinctures are solutions that contains at least 45 percent alcohol with the ration 1:4.

 

These are the ratios of herbs to menstrua:

  • Tinctures of dried herbs : 20 gm of dried herb in 100 ml of tinctures (1:5 or 20%)
  • Tinctures of dried toxic herbs : 10 gm of dried herb in 100 ml of tinctures (1:10 or 10%)
  • Tinctures of fresh herbs : 50 gm of fresh herb in each 100 ml of undiluted ethyl alcohol (1:2 or 50%).

 

The dosage depends on the herb. Tinctures are more concentrated than either infusions or decoctions.

The concentration of alcohol varied between 40 percent to 60 percent. One of the best choice is a eighty-proof vodka that is a 40 percent alcohol by volume. Hundred proof represent a 50 percent alcohol by volume. Only 30 percent alcohol is sufficient to preserve a tincture. For the dried plant preparation, 40 percent is adequate. But with the fresh plant, because of the juice, maybe a 50 percent is more judicious.

Tincture recipe for dry plant : Grind dried herb to a powder. Weigh the plant. Place the powder into a large jar with a top. Add the alcohol. Stir the mixture well and add enough menstruum to the wet herb (¼ inch of extra menstruum sits atop the herb). If the her is floating, add ¼ inch below the herb. Cap jar tightly and check the jar after one day to check the menstruum. Some herbs absorbed it. You can add extra liquid if it happen. Shake the tincture for 14 days. Day 15, pour off the clear tincture from the top. Press the remaining wet pulp and combine these two liquids. Filter. Bottle.

Tincture recipe for fresh plant : Chop and weigh the fresh plant into a small pieces and stuff them into a canning jar. Filling it to the top and pack the herb into the jar very tightly. Add 190 proof ethyl alcohol. Filling the jar to the top and make sur all the herb is covered by the alcohol. Cap jar tightly. Shake the tincture for 1 days. Day 15, decant the liquid, press the remaining wet pulp and combine the two liquids. Filter and bottle.

 

Tincture by percolation

Maceration consists by extracting soluble constituents by simply soaking them in a solvent. But percolation is a process of extracting the soluble constituents of an herb by the slow passage of a solvent through a column of dried powdered plant which has been packed in a percolator.

The percolation process offers a tincture in 24 hours whereas maceration ordinary takes 14 days, sometimes longer. Percolation is easier and faster to prepare more highly concentrated dry plant tinctures and fluid extracts. The soluble constituents of an herb can be collected more completely by percolation than by soaking or pressing. The liquid left in the residue is pure menstruum.

To prepare the percolation, you need a percolator cone. The transmogriefied water bottle that  will sit upside down could be a glass canning jar. You can also need a packing rod.

 

Recipe :
  • Grind and sift your dried plant. Run the powder through your sifter and remove all chunks.
  • Weigh the freshly ground herb. Pack the herb into a measuring cup to determine the compressed volume that herb fills (exemple : 200 ml). A volume of menstruum will be retained by the marc and discarded along with the marc at the completion of the percolation. For these reason, an amount of menstruum must be added to the full volume of menstruum that is required to produce a 1:5 tincture. This extra menstruum will be added to your original mensrtuum (800 ml + 200 ml).
  • Prepare the menstruum of 40% to 60% alcohol, 60% of 190-proof ethyl alcohol or 40% of distilled water.
  • Moist the herb slowly before the herb is packed into the cone. Add approximately 200 ml of menstruum to the powered herb and mix it. The mixture must be moist enough but not gets too moist.
  • Place the moistened powder into a container that can be tightly sealed to prevent evaporation and let it sit for 1 hour to 6 hours.
  • Pack lightly a coffee filter cone with some of the moist powder.
  • Slide the filled paper cone down into the neck of the glass percolator cone. Once it is in place, make sure the paper cone is adhering to the glass and is sealed completely around.
  • Gradually add more of the moist powder on top and tamp it down evenly with the packing rod. Be sure the top surface of the final layers is flat and level.
  • Lay a second piece of filter paper coffee on top of the packed herbs. If you ant, you can place a quartz crystal to weigh the paper down.
  • Set the packed percolator down into the cane jar. Make sure the top surface of the powder is level.
  • Slowly pour the menstruum onto the column of herb.
  • Having made sure that at least one inch of menstruum covers the top of the moist powder, so no air gets into the column.
  • Cover the cone with a plastic bag.
  • Left the herb macerate for at least 12, hour but 24 or 48 hours is the best.
  • After the period of maceration, remove the plastic bag, let the menstruum carrying with the extractive to drip slowly into the cane jar. Slowly lift the cone and set it in a second jar to continue dripping.
  • Continue to add fresh menstrum until it all drips through.
  • Observe the quantity of tincture in the jar versus the among of menstruum remaining. The next time, you can adjust the extra menstruum depending on the herb used.

Wine and Vinegar infusion

Wine infusion

Wine is characterized as a spirituous liquid, the result of the fermentation of grape juice. The other ingredients of the wine are ugar, gum, tannic, malic, acids, coloring, tartrate of lime and volatils oils (bouquet).

Medicated wines are one of the oldest class of Galenic preparations. They are hydro-alcoholic solutions made from various plants and employing white or red wine as the principal solvent. The acid that wine usually contains serves in some instances to increase its solvent power.  Herbal wines seems to have a more festive relationship with the human mind and body.

Wine using for medicinal therapies needs to be a premium quality. The primary propertie of wine is antispasmodic. Medicated wines are relatively low alcohol content tinctures prepared usually by maceration. The dosage depend one each person, but in general, a tablespoonful two or three times a day is required.

There is a variety of wine used in pharmacy for making medicated wines : grape wine, sherry wines, port, sparkling wines, apple cider, madeira, mead, grand marnier and claret.

Recipe :

  • Reduce the dried herb to powder.
  • Combine with pure wine of your choices.
  • Macerate for 14 days and shaking the mixture frequently.
  • Pour into a sterilized bottle, cap and store in a cool location.

 

Vinegar infusion

Vinegar is an aromatic sour liquid formed by a two step fermentation. The first step is accomplished when microorganisms turn sugar-containing liquids into alcohol. These base can be sugar and water mixture or a fruit juices. The second step is accomplished by the microorganisme nammed Mycoderma aceti which takes over and turns the alcoholic liquids into a dilute acetic acid. The microorganisme is resident in all air.  The transition of alcohol to vinegar can take about four months if you are using a mother. But sometmes, it can take merely a few weeks to upp to six months depending on the temperature during the fermentation.

Vinegar who is a derivative of apples or grappes, contains sugar, starch and gum. The fruits contains minerals salts. Vinegar has the advantage to be pure and naturally fermented.  It is an excellent tonic for the digestive tract and can help the boby to regulate its acid/alkaline balance.

Medicinal vinegar is agood alternative for those who resist the use of alcohol. The best vinegar contains the natural “mother” of vinegar. This mother can be filtred out and passed on from batch to batch.

Pure vinegar is know for promotes the flow of saliva, helps alleviate restlessness, promotes the secretion of the kidneys and respiratory mucus membranes, diminish  the frequecy of the pulse and the heat of the skin.

Medicinal vinegars are intended for internal or external use. It is made by macerating medicinal plnta in vinegar. You can do a medicinal vinegar by infusing leaves and flowers or by infusind roots and barks. Note that for the root, you need to heat the infusion to the boiling point afer the strain.

Recipe :

  • Reduce the dried herb to a powder.
  • Combine with pure undiluted vinegar. The weight to volume depend on the plant. It is between 1:2 to 1:5.
  • Macerate for 10 to 14 days and skake the mixture frequently.
  • Strain, filter, pour into sterilizes bottle and cap.

Types of solvent in Herbal medicine

There are 5 type of solvents that are used traditionaly in herbal medicine : water, vinegar, ethyl alcohol, wine, oil. Water is a remarkable solvency extracts for diverse substances. Vinegar is generally classed among the derivatives of alcohol because it is produce by the oxidation of alcoholic liquides. Wine could be a good solvent for the herbs. In ayurvedic medicine, the use of wine is a part of the pharmacopeia. Ayurveda calls Draksha the medicated wine used for a variety of remedies. Ethyl alcohol is a good solvent for extracting resins, essential oils, glycosides, chlorophyll, alkaloids and bitter constituents. Oil is a good solvent too. Ayurvedic medicine use ghee that is a clarified butter. Ghee is a very good substance to improve the absorption of medicinal properties of herbs particularly those who heal the nervous system.

Water 

Called the universal solvent, water is the most abundant solvent available on this planet. The cold water is a good solvent for plant constituents (proteins, coloring matter, tannins, mucilaginous substances), but hot water implicated that the plant swell and burst the cells. It is important to know the medicinals properties of a plant to chose the good water extraction. Heating a water menstruum encourtered disadvantage like the separation out from the solution.

Vinegar

The use of apple cider vinegar is request but we also use the rice vinegar, plum vinegar or balsamic vinegar. The vinegar is a sour liquid on account of acetic acid. It has valuable properties as a solvent. The role is to fix and extract certain alkaloids and can be substituted for alcohol. Vinegar’s action is excellent for the preservative of herbal properties. Pure vinegar preparations are said to be more liable to change than tinctures. Vinegar is commonly added as 5 percent to 10 percent of an alcohol-based for adjusting the pH.

Wine

The maceration of the herbs in wine is a highly recommended. Wine has a low alcoholic content. White win is preferred as menstrua for making medicinal wines because of their small proportion of tannins. With 16% herbs we use 24% of alcohol.

Ethyl alcohol

Alcohol do not abstract mucilaginous, gums, starch, albuminous materials. Alcohol paralyzes enzymes and prevent the growth of yeast, fungi and most bacteria.  It has the advantage to eliminate the microbial activity, inactivate the enzymatic action which most of the time destroy the alkaloids and glycosides. Alcohol can be mix with water in all proportions for many active plant substances.

Oil

Fixed oil are obtained from both vegetable and the animal kingdom. There are insoluble in water but are capable of being mixed with water with the assistance of mucilage. The oils are decomposed in the intestine by the digestive juices into fatty acids.

 

Infusion : Methods of preparation

An infusion is a liquid preparation made by treating fresh or dehydrated vegetable substances. The nutritional and medicinal principles are extract with cold or hot water. The infusions can be made in three ways which are maceration, digestion and percolation. Maceration consist by soaking chopped herb in a menstruum until complete dissolution. Digestion is a maceration subjected to moderate continual heat below boiling temperature.

The herbs contains a valuable volatile constituent, the use of cold water is a better choice (chamomile, peppermint). We use the cold water when the herb contains a constituent that is not desired and not readily dissolved by cold water (safran). Some principle could be deteriorate by the hot water like Wild Cherry bark.

The infusions made with boiling water extracted starch. The cold water extracted albumin (plant protein), but the gum, sugar and other extractive are dissolved by the both.

The most suitable vessels for infusions are made of glazed earthenware, porcelain or glass. When the plant contained an astringent constituent, the iron, aluminum and other metallic vessels are unsuited.

Hot infusion is made by pouring boiling water upon the herb. We can let it stand for 20 minutes in a warm place. For some herbs, it is important to strain and press out the marc (pulp) for bulky herbs and flowers. This method retain a considerable proportion of the extract.

Cold infusions are made by putting the herb into the water for overnight at room temperature. It is recommended to suspend the herb in a small cotton pouch and to squeeze out when the infusion process is completed.

Cold infusion : burdock root, chamomille, cleavers, comfrey root, crampbark, marshmallow root, mugwort, nettle, peppermint, uva ursi, slippery elm.
