Some modern prescription drugs are based on plant extracts rather than whole plants. The phytochemicals may be synthesized, compounded or otherwise transformed to make pharmaceuticals. Examples of such derivatives include aspirin, which is chemically related to the salicylic acid found in white willow. The opium poppy is a major industrial source of opiates, including morphine. Few traditional remedies, however, have translated into modern drugs, although there is continuing research into the efficacy and possible adaptation of traditional herbal treatments.

It came into use in treating cardiac disease in late 18th century England in spite of its high toxicity.a Its use has been almost entirely replaced by the pharmaceutical derivative Digoxin, which has a shorter half-life in the body, and whose toxicity is therefore more easily managed.[54] Digoxin is used as an antiarrhythmic agent and inotrope.[55]

Bark (and to a lesser extent the fruit) has been used as a laxative, due to its 3 – 7% anthraquinone content. Bark for medicinal use is dried and stored for a year before use, as fresh bark is violently purgative; even dried bark can be dangerous if taken in excess.[76]
Traditionally thought to be good for the eyes and to remove skin blemishes. In modern times herbalists use it to treat skin diseases and conjunctivitis, as well as to cleanse the kidneys. However, Howard (1987) warns that fumitory is poisonous and should only be used under the direction of a medical herbalist.[77]
It produces a specific kind of tannins called hamamelitannins. One of those substances displays a specific cytotoxic activity against colon cancer cells.[85]
The leaves are used as herbal medicine to alleviate cough and fever, pain, and general gastrointestinal disorders as well as to cure dermatologic disorders. Similarly, the fruit juice and oils can be used in the treatment of liver disease, gastrointestinal disorders, chronic wounds or other dermatological disorders.[86]
Although used traditionally by Native Americans to treat skin diseases and ulcers, there is no scientific evidence to support the use of goldenseal for treating any disease.[88]
It is the major source of the chemical compound shikimic acid, a primary precursor in the pharmaceutical synthesis of anti-influenza drug oseltamivir (Tamiflu).[93]

In the traditional Austrian medicine Plantago lanceolata leaves have been used internally (as syrup or tea) or externally (fresh leaves) for treatment of disorders of the respiratory tract, skin, insect bites, and infections.[18]
The extracts and purified platycoside compounds (saponins) from the roots may exhibit neuroprotective, antimicrobial, anti-inflammatory, anti-cancer, anti-allergy, improved insulin resistance, and cholesterol-lowering properties.[121]
