How to Prepare Thumbai

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.

Poultice (Topical Compress)Easy · 10-20 minutes

Equipment

Fresh or dried herbs, Clean cloth or gauze, Hot water, Bowl

Instructions

1FOR FRESH HERBS: Chop or mash fresh plant material. Apply directly to the skin, cover with a clean cloth.
2FOR DRIED HERBS: Mix dried, powdered herb with enough hot water to form a thick paste.
3Spread the paste onto a clean cloth or gauze, about 1/4 inch thick.
4Apply the herb side against the skin. Cover with another clean cloth to hold in place.
5Leave on for 20-30 minutes, or until cooled. Reapply as needed.
6For a warm poultice, wrap a hot water bottle or warm towel over the cloth.

Tips

1Standardized extracts are professionally manufactured to contain a guaranteed amount of active compounds.
2Follow the dosing instructions on the product label.
3Take with food unless otherwise directed.
4Choose extracts from companies that provide third-party testing (USP, NSF, or ConsumerLab verified).
5Common standardizations: Milk Thistle (80% silymarin), Ginkgo (24% flavone glycosides), Turmeric (95% curcuminoids).

Tips

• Standardized extracts provide consistent dosing — important for herbs where potency varies.
They are stronger than whole-herb preparations and may have different effects.
