- The Pygeum africanum (African plum) tree is a tall evergreen of the family Rosaceae found in central and southern Africa. Its bark has been used medicinally for thousands of years. Traditional African healers have used the bark to treat bladder and urination disorders, particularly symptoms associated with benign prostatic hypertrophy (BPH), which is an enlarged prostate. Historically, the bark was powdered and used to make a tea, which was taken by mouth for these conditions.
- The African plum tree has become endangered due to the demand for its bark to process Pygeum africanum extract.
- The majority of trials conducted since the 1970s report improvements in BPH symptoms, including frequency of nighttime urination, urine flow rate, and left over urine volume, with the administration of Pygeum africanum bark extract. This research has led some credibility to the common use of this agent in Europe for BPH. The herb is less commonly used in the United States where prescription drugs or the herb saw palmetto is more commonly used.
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.
*Key to grades:
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Adults (18 years and older)
- For treating benign prostatic hypertrophy, 75 to 200 milligram capsules of standardized pygeum extract taken daily by mouth either as a single dose or divided into two equal doses have been studied. One clinical human trial has shown that Pygeum africanum and stinging nettle (Urtica dioica), when used in combination, were efficient in treating benign prostatic hypertrophy and its symptoms.
Children (younger than 18 years)
- There are not enough scientific data to recommend pygeum for use in children and there are potential side effects.
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.
- People with known allergies to pygeum should avoid this herb.
Side Effects and Warnings
- Pygeum has been well tolerated in most studies, with adverse effects similar to placebo (sugar pill). Some people may experience stomach discomfort including diarrhea, constipation, stomach pain, or nausea. Stomach upset is usually mild and does not typically cause people to stop using pygeum.
- Safety of use beyond 12 months has not been reliably studied.
Pregnancy and Breastfeeding
- Pygeum cannot be recommended during pregnancy or breastfeeding because of a lack of scientific information and possible hormonal effects.
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.
Interactions with Drugs
- Use of pygeum with other drugs commonly used to treat symptoms of prostate enlargement, called 5-alpha-reductase inhibitors, such as terazosin (HytrinÂ®) or finasteride (PropeciaÂ®, ProscarÂ®), may increase beneficial effects, although this is not well studied.
- In theory, pygeum may interact with estrogen or other drugs with hormone activity (birth control pills). Although not well studied in humans, pygeum may have anti inflammatory and anti-cancer effects.
Interactions with Herbs and Dietary Supplements
- Pygeum may result in increased beneficial effects for the prostate if used with (Serenoa repens) or stinging nettle (Urtica dioica). Combination products are available containing both stinging nettle and pygeum.
- Pygeum may interact with herbs/supplements containing chemicals with estrogen-like effects (“phytoestrogens”).
- Although not well studied in humans, pygeum may have anti inflammatory and anti-cancer effects.
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.
