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.
Evidence
DISCLAIMER:
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.
Benign prostatic hypertrophy/BPH symptoms:
Pygeum (P.africanumbark extract) has been observed to moderately improve urinary symptoms associated with enlargement of the prostate gland or prostate inflammation. Numerous human studies report that pygeum significantly reduces urinary hesitancy, urinary frequency, the number of times patients need to wake up at night to urinate, and pain with urination in men who experience mild-to-moderate symptoms. However, pygeum does not appear to reduce the size of the prostate gland or reverse the process of BPH. It is unclear how pygeum compares to the effectiveness or safety of other medical therapies, such as prescription drugs (eg. alpha-adrenergic blockers or 5-alpha reductase inhibitors), surgical approaches, or other herbs/supplements such as saw palmetto.
There is ongoing study in this area. Patients with urinary symptoms or BPH should speak with their healthcare professional about the various available treatment options.
Grade: B
Tradition
WARNING:
DISCLAIMER:
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.
Dosing
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.
Safety
DISCLAIMER:
Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Allergies
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.
Interactions
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 (Hytrin®) or finasteride (Propecia®, Proscar®), 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).
Interactions with Herbs and Dietary Supplements
Pygeum may result in increased beneficial effects for the prostate if used with saw palmetto (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").
