How to Prepare Mai Men Dong

Decoction (Roots, Bark & Seeds)Easy · 25-45 minutes

Equipment

Pot with lid (non-aluminum), Strainer, Measuring spoon, Stove

Instructions

1Place 1 tablespoon of dried root, bark, or seeds per 12 oz of cold water in a pot.
2Bring to a boil, then reduce heat to a low simmer.
3Cover and simmer for 20-40 minutes. Harder roots (like Astragalus) may need up to 45 minutes.
4The liquid should reduce by about one-third.
5Strain through a fine mesh strainer, pressing the herbs to extract all liquid.
6Drink 1-3 cups daily. Can be combined with honey or blended with an infusion.

Tips

• Use a non-aluminum pot — aluminum can react with plant compounds.
• Decoctions are necessary for roots, bark, seeds, and mushrooms — these are too tough for simple steeping.
• You can simmer mushrooms (Reishi, Chaga) for 2+ hours for stronger extraction.

Some roots are very potent — follow specific dosing guidelines for individual herbs. Avoid decocting herbs with volatile oils (peppermint, chamomile) as you will lose the beneficial compounds.

Refrigerate and use within 48-72 hours. Can be gently reheated.

Capsules (Powdered Herb)Moderate · 30-60 minutes per batch

Equipment

Herb grinder or pre-powdered herb, Empty vegetarian capsules (size 00 or 0), Capsule filling machine (optional but recommended), Small bowl, Scale (optional for precision)

Instructions

1If using whole dried herb, grind to a fine powder using a dedicated herb grinder.
2Pour the powdered herb into a small bowl or capsule filling tray.
3Separate the capsule halves. Fill the larger half with powder, tapping to pack gently.
4Press the smaller half onto the larger half to seal.
5A size 00 capsule holds approximately 500-700mg of powdered herb.
6Standard dosing varies by herb — typically 1-3 capsules, 2-3 times daily with food.

Herbal Tea (Infusion)Easy · 10-15 minutes

Equipment

Kettle or pot, Mug or teapot, Strainer or tea infuser, Measuring spoon

Instructions

1Bring fresh water to a rolling boil (200-212°F / 93-100°C).
2Place 1-2 teaspoons of dried herb (or 1 tablespoon fresh) per 8 oz cup into your strainer or infuser.
3Pour hot water over the herbs and cover to prevent volatile oils from escaping.
4Steep for 10-15 minutes for medicinal strength (5 minutes for a lighter, everyday tea).
5Remove the strainer/herbs. Add honey, lemon, or other herbs to taste if desired.
6Drink 1-3 cups daily, or as directed by a qualified herbalist.

• A capsule filling machine makes the process much faster and more consistent.
• Pre-powdered herbs from reputable suppliers save significant effort.
• Store finished capsules in a cool, dry place in an airtight container.

Capsules bypass taste, which can be important — bitter taste stimulates digestion. For digestive herbs, teas or tinctures may be more effective. Always follow recommended dosing.

Store in airtight containers away from moisture. Use within 6-12 months for best potency.

• Covering while steeping is important — it traps beneficial volatile compounds.
• Leaves and flowers generally need 10-15 minutes; roots and bark need a decoction instead.
• Make larger batches and refrigerate for up to 48 hours.

Start with a small amount to check for any sensitivity. Not all herbs are suitable for tea preparation — some require alcohol extraction (tincture) for full potency.

Drink fresh or refrigerate for up to 48 hours. Dried herbs should be stored in airtight containers away from light.
