Here is the short version: the botanicals traditionally reached for in Post-Meal Bloating, Sluggish Digestion & Soothing Gut Mucilage only perform the way the old herbals describe when three things line up — the right species (Centella asiatica, Avena sativa, Handroanthus impetiginosus, Taraxacum officinale), the right plant part at the right freshness, and the right preparation method. Get one wrong and you are drinking flavored water. Get all three right and you finally understand why these plants have been kept on apothecary shelves for centuries.

Frequently Asked Questions

How do I prepare Organic Gotu Kola Herb Cut & Sifted for the best result?

Traditional Covered Infusion: Steep 1 to 2 teaspoons of cut botanical per 8 oz freshly boiled spring water (205°F) in a covered vessel for 10–15 minutes to retain volatile aromatics, then strain through fine mesh. See the preparation table above for grams, water temperature, steep time, and extraction ratio.
