Herbal Solvents and When to Use Them
Updated: Feb 8
Learning to make your own herbal remedies can be exciting and rewarding. But how do you know what solvent to use for your plants?
Part of learning about plants and their healing properties is learning what part you want from the plant and what solvent best achieves that goal.
The main solvents used in remedy making are alcohol, water, vinegar, glycerin and oil.
Water is most often used to extract vitamins, minerals, mucilage, polysaccharides, volatile oils, proteins, some alkaloids, and glycosides. Water is readily available but not very shelf stable. Water based preparations last between 36- 48 hours at room temperature before going off. Examples of water-based prep are teas, infusions nourishing herbal infusions and decoctions, which is reducing a tea by half by simmering it. Examples: Elderberry, Peppermint, Tulsi, Hawthorn berry

Alcohol is used to best extract essential oils, resins, alkaloids, and glycosides. Alcohol tinctures can last 5 years or more and make good use of expensive or scarce plants as they are dosed by the drop. Examples, Echinacea, Motherwort, Dandelion root, Osha root

Vinegar extracts minerals very well and is often used for tonic preparations. Vinegar tinctures last 2-5 years. They can be used for internal or external uses.
Examples, Yellow dock root, Mugwort, Nettle

Glycerin is used to extract hormonal precursors, glycosides, and some volatile oils. Glycerin is sweet so children and sweet toothed adults usually do not object to taking these remedies. They last 2-4 years.
Examples: Rose, chamomile, lilac, lemon balm, violet flowers
Oils are used to extract fatty acids, terpenoids, waxes, and triglycerides.
These preparations last as long as the base oil lasts, from 3 months to 2 years.
Examples Calendula, Plantain, Comfrey, Dandelion flower, St John’s wort
