Traditional Chinese Medicine, Assembled in the USA

Founded in 1986 by Joel, Betty, and Noah Schreck, Dr. Shen’s Chinese Herbs grew out of Berkeley, California’s Shen Clinic. Within a few years, they became aware of quality and purity issues with the imported Chinese herbal medicines they were selling at the clinic. Testing revealed that many of the imported Chinese medicines contained impurities, unlisted drugs, and low grade raw materials. In 1994, they began manufacturing the Dr. Shen Chinese herbal line of products in the USA, in modern cGMP approved factories, using the finest grades of herbs. Their goal was to make a better, safer product using premium grade herbs, modern tabulating methods, and compliant labels.

To make their products, Dr. Shen’s begins with whole herbs, not herbal powders, which allows for a thorough visual inspection in order to ensure their quality. This organoleptic inspection, as well as laboratory testing for purity, safeguard a quality product from start to finish. With great attention to detail, fully cGMP compliant partners in the USA do all the milling, mixing, baking, tabulating, and packaging. Each batch is tested for dissolvability, mold, microorganisms, heavy metals, and other impurities. Standardized powders extracted with chemical solvents are not used. Tablets are bound with a proprietary mixture of simple excipients, and then stamped, baked, and coated with a thin vegetable glaze; making them easy to swallow.

No sugar coating, dyes, drugs, or chemical solvents are used. Wildcrafted and organic herbs are included whenever possible. Dr. Shen’s will never use an endangered species, plant or animal. As of 2017, our entire line is Gluten Free.

Today, Dr. Shen’s is available online and in thousands of natural food and vitamin stores throughout the USA.

Though the company is best known for its three outstanding cold products — DR. SHEN’S YIN CHIAO, for colds starting in the throat, DR. SHEN’S GAN MAO LING for colds in the nose, and DR. SHEN’S ZONG GAN LING for colds beginning with a headache, fever, and fatigue — they also make Chinese herbal remedies for allergies, immunity, hair loss, menopause, nausea, constipation, and other conditions that will usually benefit more from Chinese herbs than from Western medicines.  They do not make products to treat serious illnesses that require a doctor’s care. Customers are encouraged to seek the advice of a Health Care Practitioner for these more serious conditions.
