If you’ve ever finished a cup of herbal tea and wondered whether it actually did anything, you’re asking the right question.
The honest answer is: it depends on how you made it.
Herbal tea and plant medicine can look identical in the cup. Every tea may be a water infusion, but not every water infusion is tea – with intention, it can be medicine. We must bring our attention to the attributes and constituents of the plants we intend to use, and from there, our method can be determined. This intention, this attention, is the defining factor between tea and medicine.
Here’s the framework I use and teach for every water-based preparation.
Foundations of practice
At its core, a water infusion requires water, heat, plant material, and time. Before making any decisions, we must explore the complexities and develop a system that enables us to create simple, effective medicine.
Whether preparing tea or medicine, attention to water quality is essential, and depending on where in the world you live, access to clean drinking water can be very limited. Filtered water is the most reliable choice – consistent, clean, and free of chlorine, heavy metals, and impurities that can alter the chemistry of your preparation and your health over time. Tap water varies significantly depending on where you live. If filtered water isn’t accessible, it’s worth understanding what’s in yours. What you’re dissolving your medicine into is part of the medicine.
Plant Medicine
The importance of understanding how and why a plant is an appropriate medicine before using it cannot be overstated. The mindset that plant medicine is safe because it is natural glosses over its power. The very first step in determining our preparation method is conducting research on the condition we are treating, the recommended plants for treatment, and whether those plants are appropriate, including any contraindications relevant to the individual.
Phytochemicals are bioactive substances found in edible plants that protect plants against UV radiation, pests, and pathogens. They have been shown to offer significant human health benefits, including antioxidant, antimicrobial, anti-inflammatory, and anticancer effects, by interacting with our body systems. Their bioavailability and bioactivity after ingestion depend on their solubility and absorption characteristics. The compounds, or phytochemicals, of a plant directly correlate with the medicine’s mechanism and determine which ingestion (absorption) and extraction (solubility) methods are appropriate.
Bioavailability describes how much of that compound is absorbed and can be used by tissues and organs. Bioactivity describes how effectively a plant compound actually does something useful in the body — not just that it’s present, but that it produces a real, measurable effect on health. These bioactive substances can be extracted from the plant using solvents such as water, alcohol, and oil, and may degrade when exposed to pH changes, heat, light, and oxygen. For example, a water infusion is used when a plant’s compounds are water-soluble, and a recipe might suggest infusing in a dark cupboard to avoid light degradation.
Phytochemicals and their functions
This is not an exhaustive list.
Flavonoids: (quercetin, catechins) Are responsible for vivid colors (red, yellow, blue) and contribute to pungent, bitter, sweet-tart flavor profiles. They act as antioxidants, reduce inflammation, support cardiovascular health, and inhibit cancer cell growth. Tea, cocoa, apples, and onions.
Terpenoids: (beta-caryophyllene, limonene, pinene) Are responsible for giving plants their unique scents, flavors, and colors, often acting as a natural defense mechanism against pests and predators, harsh weather, environmental stressors, and disease, while also attracting beneficial insects for pollination. These compounds act as “chemical sign language” for plant communication. They offer potent anti-inflammatory, mood-altering, and anti-aging properties and act as natural remedies for pain, anxiety, and infection. Cannabis, herbs, and citrus.
Polyphenols: (resveratrol, tannins) Create bitter, pungent, medicinal, and mouth-puckering flavors. They are known for their anti-aging properties, LDL cholesterol-lowering effects, and cardiovascular health benefits. Dark chocolate, red wine, and coffee or tea.
Alkaloids: (caffeine, quinine) Contribute bitter, hot, pungent, spicy flavors which serve as a potent defense mechanism for plants. They often stimulate the nervous system or act as antiparasitics in humans. Coffee, tea, chili pepper, and tonic water.
The compounds in your plant determine everything that follows.
The methodology: how to choose your plant and your preparation
Most people start with the plant. A better place to start is the problem.
What are you trying to address? Be specific. “Stress” is not specific enough. Is it difficulty falling asleep, an overactive nervous system, or a body that can’t come down after a long day? The more precisely you can name what you’re experiencing, the more precisely you can match a plant to it.
Which plant is appropriate — and is it appropriate for you? Once you have a shortlist of plants indicated for your specific situation, contraindications are non-negotiable. Drug interactions, pre-existing conditions, pregnancy — these aren’t fine print. They’re the difference between medicine and harm. Natural doesn’t mean safe, and this step is where that truth lives.
What part of the plant are you using? A flower and a root are not interchangeable. Different plant parts contain different compounds in different concentrations, and they require different extraction methods. A delicate petal needs gentle heat and a short steep. A woody root may need a full decoction — simmered, not steeped — to release what’s inside it.
What compounds are you trying to extract? This is where your research from the previous steps pays off. If you know the active constituents of your plant and what they do, you can choose a preparation method that actually captures them. Some compounds are heat-sensitive and degrade with boiling. Others require alcohol to extract fully. Water alone won’t always do the job.
Which preparation method serves those compounds? Now you can make the decision. A standard hot infusion, a cold infusion, a decoction, a tincture — each one is a tool. Knowing which tool fits the job is the difference between a pleasant drink and a targeted preparation.
If this framework is new to you, the plant library is a good next step. Each profile applies this methodology to a specific plant: what it does, how it works, how to prepare it, and who shouldn’t use it.
If you’re ready to apply this to your specific situation, your health history, your goals, and your growing space, that’s what a strategy call is for.
