This is Frontier's nitrogen-flushed double wall silverfoil pack. Some Frontier packs are double wall wax-lined paper. Used as an infusion, decoction, extract and tincture. Aged buckthorn bark is an ingredient in laxative teas, extracts, and tablets in Europe. It is also added to sunscreens. The 1997 Commission E on Phytotherapy and Herbal Substances of the German Federal Institute for Drugs recommends Buckthorn bark for 'Constipation.' Contraindications: Intestinal obstruction, acute intestinal inflammation... Children under 12 years of age; pregnancy.' 'Side Effects: In single incidents, cramp-like discomforts of the gastrointestinal tract. These incidents require a dosage reduction. With long-term use/abuse: disturbances of electrolyte balance, especially potassium deficiency, albuminuria and hematuria.' 'Pigment implantation into the intestinal mucosa (pseudomelanosis coli) is harmless and usually reverses upon discontinuation of the drug.... Stimulating laxatives should not be used over an extended period (1 - 2 weeks) without medical advice. Because of insufficient toxicological investigation, this drug should not be used during pregnancy or lactation.' 'Interactions with Other Drugs: With chronic use or in cases of abuse of the drug, a potentiation of cardiac glycosides due to a loss of serum potassium is possible. Also possible is an effect on antiarrhythmic agents. Potassium deficiency can be increased bysimultaneous application of thiazide diuretics, corticosteroids, or licorice root.' 'Dosage: Cut bark, powder or dried extracts for teas, decoction, cold maceration or elixir. Liquid or solid forms of medication exclusively for oral use. 20 - 30 mg hydroxyanthracene derivatives daily, calculated as glycofrangulin A.' 'The fresh bark contains free anthrone and must be stored for one year or artificially aged by heat and aeration. The use of illegally processed buckthorn bark, e.g., fresh bark, will cause severe vomiting, possibly with spasms.'

In the United States, buckthorn was included in the National Formulary as an official drug from 1820 to 1830 and again from 1880 to 1910. Many Rhamnus species share anthraquinone derivative constituents and provide characteristic laxative actions. These constituents were isolated by botanists early on in the study of plant chemistry. Anthraquinone derivatives and give buckthorn heartwood a bright red-yellow color, used for centuries as a dye for textiles. Grieve's classic 'A Modern Herbal': 'Tonic, laxative, cathartic.' 'Dried seasoned bark from one to two years old alone should be used, as the freshly stripped bark acts as an irritant poison on the gastro-intestinal canal.
