A Beginner's Guide to Preparing Herbs for Medicinal Use
Herbal medicine has been used for thousands of years across cultures and continents. Today, many people are rediscovering the healing power of plants, seeking natural remedies to complement or even replace conventional medicine. But before you start brewing teas or crafting tinctures, it’s important to understand how to choose, source, and prepare herbs safely and effectively for medicinal use.
Choosing Quality Herbs
The effectiveness of an herb often begins with its quality. When evaluating herbs, ask:
-
What is the potency and freshness of the herb?
-
How was it harvested and prepared?
-
Is it ethically and sustainably sourced?
Reputable suppliers and trained practitioners are your best resources for ensuring the herbs you purchase are of high quality. Be wary of vague labels or unclear sourcing, as contamination and adulteration are not uncommon in unregulated markets.
Sourcing: Wild vs. Cultivated
Herbs can be wild-foraged or farm-grown, and both methods have pros and cons. Some herbalists advocate for sourcing herbs from their native environments, arguing that plants thrive best when grown among their "plant families" in familiar ecosystems. However, wild-foraging may not always be sustainable or accessible.
Herbalists often suggest buying herbs from local sources when possible and researching the companies you purchase from. Look for businesses that are transparent about their growing and harvesting practices, and consider supporting those that actively contribute to ecological restoration.
Fresh vs. Dried Herbs
Whether to use fresh or dried herbs depends on the intended preparation and how quickly you plan to use them. Fresh herbs are great for teas, tinctures, and poultices, but they lose potency quickly. Dried herbs are more versatile and longer-lasting, making them ideal for capsules, balms, and some internal remedies.
How to Prepare Herbs for Medicinal Use
The method of preparation significantly impacts the efficacy of the herb. Some of the most common methods include:
Internal Medicinal Preparations:
-
Infusions: Ideal for soft plant parts like leaves and flowers. Similar to making tea, simply pour hot water over dried herbs and let steep. Drink while warm.
-
Decoctions: Best for harder plant parts like roots, bark, and seeds. Simmer crushed or powdered plant material in water for 15 minutes. Strain and drink hot.
-
Tinctures: Highly concentrated herbal extracts made using alcohol and water. Steep chopped herbs in alcohol for 4–6 weeks, shaking occasionally, then strain. Tinctures have long shelf lives and are very potent.
-
Powders and Capsules: Dried herbs can be powdered and taken as capsules or mixed into drinks.
External Medicinal Preparations:
-
Compresses and Washes: Use decoctions or infusions to create a wash for skin irritations. Compresses are more concentrated and are applied with cloth to affected areas.
-
Poultices: Fresh or dried herbs are mashed into a paste and applied directly to the skin.
-
Salves and Balms: Infuse herbs into oils or ghee, then blend with beeswax to create topical remedies.
The Importance of Potency
In Ayurveda, the concept of verya refers to the potency or strength of an herb. This potency can be influenced by where and how the plant was grown, how it was harvested, and the method of preparation. Even culinary spices like black pepper can be medicinal when used correctly. When using plants as medicine potency is an important consideration.
Avoiding Contamination
Because herbs and supplements are not regulated by the FDA, it’s crucial to do your due diligence. A 2019 study found that nearly half of tested herbal products contained some form of contamination, such as:
-
Dust or pollen
-
Pesticides and heavy metals
-
Mold and fungi
-
Fillers and synthetic drugs
Buy from trusted brands, preferably those that prioritize organic farming and rigorous quality control. Consulting a qualified practitioner can also reduce your risk.
Sustainability Matters
Sustainability is not just a buzzword—it’s essential for protecting plant biodiversity and ensuring long-term access to herbal remedies. Wild-harvested herbs are often more potent but can be at risk of overharvesting. In such cases, cultivated herbs are the more ethical choice.
Increasing the diversity of plants in your medicine cabinet and supporting companies that promote ecological restoration are meaningful steps toward sustainable herbalism.
Herbal Products: Buyer Beware
Not all herbal products on the market are created equal. Packaged teas, infused chocolates, and trendy adaptogenic creams might not offer the medicinal benefits they advertise. For example, while adaptogens like ashwagandha are popular, they are not effective in topical form and are often misused in cosmetic products.
Working with Professionals
Because herbalism isn't uniformly regulated, certifications and qualifications can vary widely. The following organizations can help you find a trained herbalist:
-
American Herbalists Guild
-
National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM)
-
National Ayurvedic Medical Association
You may also choose to work with licensed naturopathic doctors or acupuncturists, some of whom are covered by insurance.

Be Prepared: Creating a Home Apothecary
Setting up a simple home apothecary is a great way to keep your most-used herbs readily accessible. That way when you need to make a preparation you have what you need right at hand. You don’t need a huge space—just a cool, dry, and dark area to store your jars, tinctures, oils, and salves. Use labeled glass containers for dried herbs, and make sure to date your preparations so you can monitor potency over time. Investing in a few basic tools—like a mortar and pestle, strainer, amber dropper bottles, and measuring spoons—can also make your herbal practice more efficient and enjoyable.
Safety and Interactions with Medications
Herbs can be incredibly powerful, but that also means they may interact with prescription medications. For example, St. John's Wort is known to interfere with antidepressants and birth control pills. Garlic and ginkgo can affect blood clotting, which may be risky for people on blood thinners. Always research potential interactions, and if you're on any regular medications, consult a healthcare provider before adding herbal remedies to your regimen. Being informed helps you avoid unintended side effects and makes your herbal journey much safer.
Final Thoughts on Preparing Herbs for Medicinal use
Herbal medicine is as much an art as it is a science, drawing from diverse cultural traditions and requiring both knowledge and care. With the right approach—grounded in research, sustainability, and expert guidance—herbs can play a powerful role in supporting your overall health and well-being.
Remember, natural doesn't always mean safe. Start slow, be curious, and consult with professionals and practitioners to get the most benefit from the world of herbal medicine. Have questions - don’t hesitate to reach out.
