My Lyme literate doc (PhD Chinese medicine; Licenced Physicians Asst.) recommends this brand for quality and because it has an extract of the whole plant for better metabolization as per natropathic principles, plus the pure active ingredient artemisinin for potency, as per mainstream allopathic medicine principles. Not as strong as or an effective substitute for the pharmaceutical anti-protozoan Mepron, but the most potent form of Artemisia I've found. This is a good deal at nearly 1/2 the usual retail price.
