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.
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.
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.

The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
Fluid extracts of 1/6-1 dram of bryonin (a constituent of white bryony), 1/4-2 grains, or 0.5-1 grams per cup of water have been given by mouth.
For treating vomiting, 300-500 milligrams of powdered bryony has been given by mouth.
To promote bowel movements, 300-500 milligrams of powdered bryony has been given by mouth.
Note: Bryony is given mainly by homeopathic practitioners in extremely small doses.
Children (under 18 years old)
There is no proven safe or effective dose for bryony in children.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Avoid using bryony in individuals with a known allergy or sensitivity to bryony, its parts, or other members of the Cucurbitaceae family.
Side Effects and Warnings
When applied to the skin, bryony may cause blisters, dermatosis (skin disease), rash, and redness.
Bryony may lower blood sugar levels. Caution is advised in people with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist, and medication adjustments may be necessary.
Use the extracts from leaves or roots cautiously, as these parts of the plant may be toxic.
Avoid the fruit from bryony or white bryony in all patients. Bryony and white bryony fruit is toxic, and eating the fruit may cause abortion, anuria (reduced urination), blisters, colic, collapse, convulsions, cramps, dermatosis (skin disease), diarrhea, dizziness, hematochezia (blood in the stools), kidney damage, nephrosis (kidney disease without inflammation), neurosis (mental disorder), paralysis, rash, and vomiting, as well as death.
Avoid using bryony in individuals with a known allergy or sensitivity to bryony or other members of the Cucurbitaceae family.
Pregnancy and Breastfeeding
There is currently a lack of scientific evidence on the use of bryony during pregnancy or breastfeeding.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
Interactions with Drugs
Bryony may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. People taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.

Interactions with Herbs and Dietary Supplements
Bryony may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
