Herbs

We put great effort into correctly identifying the species. This is a science which we are still perfecting even though we have been at it for almost 10 years. Macroscopic and microscopic examinations are employed to compliment other organoleptic (sense-derived) data such as smell and taste in determining species identification. We use the Chinese Pharmacopeia for verification where the given herb is listed in that text. For the few herbs that require chemical analysis to reliably determine correct identification we rely on laboratory testing.
Quality evaluations - We purchase herbs in small batches. This insures that Spring Wind herbs are fresh. We obtain samples of each lot before purchase to ensure the quality meets our strict standards. Herbs must be clean, fresh and of good color and sapor to meet our rigorous inspection. We use herb-specific criteria when evaluating quality.

Spring Wind (USA) which provides testing capacity has the most rigorous pesticide testing program in the industry. We accept only a ND (none detected) result on pesticide tests.Herbs are tested either by in-house vapor testing (limit of 1.0 ppm) or by lab titration for sulfites (ND only). We also test aflatoxin-susceptible herbs such as seeds and grains (and herbs such as Yan Hu Suo) for aflatoxins.
