Making herbal remedies at home comes down to choosing the right method to pull beneficial compounds out of a plant and into a form your body can use. The five core preparations, listed from simplest to most involved, are infusions, decoctions, tinctures, syrups and oxymels, and salves. Each one uses a different solvent (water, alcohol, vinegar, or oil) to extract different types of plant compounds, so the method you pick depends on what herb you’re working with and how you plan to use it.
Why the Solvent Matters
Plants contain a wide variety of active compounds, and not all of them dissolve in the same liquid. Water pulls out tannins, saponins, and polysaccharides (the soothing, gel-like compounds found in herbs like marshmallow root). Alcohol is considered a universal solvent in plant extraction because it dissolves a broader range of compounds, including alkaloids, which often need around 55% alcohol to extract efficiently. Oil captures non-polar compounds like the fat-soluble vitamins and volatile oils in herbs like calendula and comfrey.
This is the single most important principle in herbal remedy-making: match the solvent to the compounds you’re trying to extract. A water infusion of a resinous herb like myrrh will barely pull anything useful out of it, while an oil infusion of a mucilage-rich herb like slippery elm would miss its most valuable constituents entirely.
Infusions: The Simplest Starting Point
An infusion is a strong tea made from lightweight plant material: leaves, flowers, and fruits. Herbs with a high percentage of volatile oils, even if they come from thicker parts like roots or bark, are also best prepared as infusions because prolonged heat would drive off those delicate aromatic compounds. Chamomile flowers, peppermint leaves, and elderberries are classic examples.
To make one, bring water to a full boil, pour it over the herb, cover the vessel, and let it steep for 20 minutes. The cover matters. It traps steam that carries volatile oils, letting them drip back into the liquid instead of escaping into your kitchen. Use roughly one tablespoon of dried herb (or three tablespoons of fresh) per cup of water. A standard medicinal infusion is noticeably stronger than a casual cup of tea.
Decoctions: For Tough Plant Parts
Bark, roots, medicinal mushrooms, and hard non-aromatic seeds need more than a steep. Their cell walls are too dense for hot water to penetrate passively, so you simmer them instead. Place the herb in cold water, bring it to a boil, then reduce the heat and simmer with the lid on for 20 to 30 minutes.
The key distinction between an infusion and a decoction is whether the herb goes into already-boiled water (infusion) or heats up with the water from the start (decoction). If you’re working with a blend that includes both leaves and roots, make the decoction first, strain it, then pour the hot liquid over the lighter herbs and steep for 20 minutes. This way each plant part gets the extraction method it needs.
Tinctures: Alcohol-Based Extracts
Tinctures are concentrated liquid extracts made by soaking plant material in alcohol for several weeks. They’re shelf-stable for years, easy to dose by the drop, and extract a wider range of compounds than water alone. A typical adult dose for most common herb tinctures is 20 to 40 drops, taken three times a day.
Choosing Your Alcohol Percentage
The alcohol content you need varies dramatically depending on the herb. Leaves generally require lower percentages, while resins demand much higher ones. Here’s a rough guide:
- 25 to 40% alcohol: Suitable for many roots (chicory root at 30%, devil’s claw at 40%) and some mild leaves (bearberry leaf at 25%).
- 45 to 60% alcohol: Works for more aromatic leaves and flowers (mullein leaf at 45%, yarrow leaf and flower at 60%) and tougher roots like black cohosh at 60%.
- 70 to 95% alcohol: Reserved for very resinous materials. Myrrh resin and propolis both require 95% alcohol to dissolve properly.
Standard 80-proof vodka is 40% alcohol, which covers a decent range of herbs but falls short for anything resinous or highly aromatic. For herbs requiring 60% or higher, you’ll need high-proof grain alcohol like Everclear (75 to 95% depending on the version available in your state).
The Folk Method
The simplest approach, called the folk method, doesn’t require a scale. Chop your herb finely, fill a clean glass jar about halfway with dried herb (or two-thirds with fresh), and pour alcohol over it until the plant material is completely submerged with about an inch of liquid above. Seal the jar, label it with the herb name and date, and store it in a cool, dark place. Shake it every day or two. After four to six weeks, strain through cheesecloth and squeeze out as much liquid as possible. Store the finished tincture in dark glass bottles.
Fresh herbs contain water, which dilutes the alcohol. If a recipe calls for dried material and you’re using fresh, you’ll need roughly three times the volume of fresh herb to equal the same amount of dried. You may also want to start with a higher-proof alcohol to compensate for the water content in the fresh plant.
Syrups and Oxymels
Herbal syrups are simply strong decoctions or infusions sweetened with honey, making them especially useful for throat-soothing or respiratory blends that need to taste palatable. The standard approach is to reduce a decoction by about half through simmering, strain it, then stir in an equal volume of honey while the liquid is still warm. Refrigerate and use within a few weeks, or add a small amount of alcohol (a tablespoon or two of brandy per cup) to extend the shelf life.
An oxymel takes a different path, combining honey and vinegar as the extraction medium. Traditional oxymel recipes use a ratio of five parts honey to one part vinegar, with the herbs steeped directly in this mixture. Apple cider vinegar is the most common choice. Pack a jar loosely with your chosen herb, pour the honey-vinegar blend over it, and let it steep for two to four weeks before straining. Oxymels work well for herbs that are too bitter or strong-tasting for a simple syrup, and the vinegar adds its own extraction power for mineral-rich plants like nettles.
Salves: Oil-Based Topicals
A salve is an herbal oil thickened with beeswax into a semi-solid form you can apply to skin. Making one is a two-step process: first you create an infused oil, then you add beeswax.
To infuse oil, fill a jar with dried herb (fresh herbs can introduce moisture that causes mold) and cover with a carrier oil like olive, sweet almond, or coconut oil. Let it sit in a warm spot for four to six weeks, shaking occasionally. For a faster version, gently heat the oil and herbs in a double boiler on the lowest setting for two to three hours, never letting the oil smoke or bubble. Strain through cheesecloth.
To turn infused oil into a salve, use a ratio of one part beeswax to four parts oil by weight for a medium-firm consistency. Melt the beeswax into the warm oil, stir until combined, and pour into tins or small jars. It sets as it cools. If you want a softer salve (more like a balm for lips or cuticles), use less beeswax. For a harder bar-style salve, add more. You can test the consistency by dipping a spoon into the mixture, letting it cool for a minute, and adjusting before you pour.
Keeping Your Workspace Clean
Contamination is the fastest way to ruin a batch. Mold in an oil infusion, bacteria in a syrup, or sediment in a tincture all come from the same source: dirty equipment or excess moisture.
Sterilize glass jars before use by placing them right side up on a rack in a pot, filling with hot water to one inch above the jar tops, and boiling for 10 minutes. If you live above 1,000 feet elevation, add one extra minute of boiling for each additional 1,000 feet. Let the jars drain upside down on a clean towel and fill them while still hot.
Always use completely dried herbs for oil infusions and salves, since water trapped in plant material creates a breeding ground for mold. For tinctures, the alcohol itself acts as a preservative, so fresh herbs are fine as long as they’re fully submerged. Label everything with the herb name, solvent, and date. This sounds tedious until you’re staring at three identical jars of dark liquid six weeks later with no idea which is which.
Storing Your Finished Remedies
Each preparation has a different shelf life depending on its solvent. Tinctures last the longest, often three to five years or more, because alcohol is a powerful preservative. Store them in amber glass dropper bottles away from direct sunlight. Salves keep for one to two years if made with dried herbs and stored in a cool place. Syrups and oxymels last a few weeks in the refrigerator without added alcohol, or a few months with it. Water-based infusions and decoctions are the most perishable and should be used within 24 to 48 hours, or refrigerated and consumed within three days.
Cool, dark storage is the universal rule. Heat degrades active compounds, light breaks down color and potency, and temperature fluctuations cause condensation inside containers. A kitchen cabinet away from the stove is fine for most preparations. Avoid the bathroom, where humidity and temperature swing with every shower.
