White bryony (Bryonia alba, Bryonia dioica)

While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.

  • Note: This monograph does not discuss black bryony (Tamus communis), which is a common name for a different plant.


  • White bryony (Bryonia alba and Bryonia dioica) is a perennial, climbing herb with flowers and lobed leaves that resemble an open hand. The plant’s berries are considered poisonous.

  • The root of white bryony has been extracted with alcohol and used at very low doses in homeopathic medications for fevers and dry mouth, respiratory infections, gastrointestinal disorders, and joint pain (applied to the skin). Some homeopathic practitioners believe that the patients who may experience the best outcome with bryony treatment are those who are initially reluctant to move or speak and who feel irritable and weary.

  • However, the homeopathic medicine bryonia was correctly identified only 48.1% of the time by homeopaths when compared with a placebo-containing bottle. In separate research, 60% of homeopaths correctly identified the bottle containing bryonia.

  • Limited research has shown that white bryony may have analgesic (pain-reducing), anti-inflammatory, and antimicrobial effects. However, clinical studies in humans are lacking.

Scientific Evidence


These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Exercise performance enhancement

There is insufficient evidence available to discuss the ability of Bryonia alba to normalize body functions, strengthen body systems, and protect the body from environmental and emotional stress, which could enhance exercise performance. Further research is required in this field.


There is insufficient available evidence to discuss the use of white bryony for pain. White bryony has been examined as part of a homeopathic preparation, but results are not promising. Further research is required in this field.
