Mukombero Doesn’t Boost Stamina and Energy, Medics Warn

NAIROBI, Kenya — Medical experts are urging Kenyans to stop treating mukombero as a natural booster for stamina, energy or sexual performance, warning there is no conclusive scientific evidence to support the widespread claims.

The root, locally known as mukombero and scientifically identified as Mondia whitei, grows mainly in Kakamega Forest and other parts of Western Kenya. It is traditionally chewed raw, brewed into tea or soaked in beverages by men who believe it improves blood flow, relaxes muscles, raises energy levels and acts as a gentler alternative to drugs like Viagra.

However, urologists say these beliefs are not backed by robust clinical research.

“There is no conclusive scientific evidence proving that mukombero treats erectile dysfunction,” said urologist Dr Edward Mugalo.

He explained that erectile dysfunction is usually caused by underlying medical or psychological issues — including diabetes, hypertension, low testosterone, stress, anxiety or depression — and requires proper diagnosis, not self-medication with unproven herbs.

Silvas Lisamula, a Luhya elder and former director of culture in the Ministry of Culture and Heritage, defended the root’s traditional role. He said mukombero has long been used during social gatherings and long cultural events to keep people alert, energised and confident.

“It was mainly used to keep people active and focused,” Lisamula told The Star at his home in Shinyalu, Kakamega County.

Botanist Dennis Omayo acknowledged that the root contains useful micronutrients such as magnesium, calcium, zinc, Vitamin D and Vitamin K. He described its effects as gradual and gentler than Viagra, but still cautioned: “It can perform like Viagra, but from a distance.”

Dr Mugalo stressed that while some men report feeling more energetic after using mukombero, this could be placebo effect or simply the result of the root’s mild stimulant properties — not proof it fixes sexual health problems.

He warned especially against its use by people with hypertension or other chronic conditions, saying unregulated herbal remedies can sometimes worsen existing health issues.

The experts are calling for better public education: men experiencing persistent fatigue, low energy or erection difficulties should visit a doctor for proper evaluation rather than depending on traditional roots alone.

Proven medications for erectile dysfunction are available and work within minutes when prescribed correctly, they added.

The caution comes as mukombero continues to gain popularity across the country, with some vendors even selling it in dried form or as packaged drinks.

While cultural leaders want the tree protected as part of Kenya’s heritage, medical professionals insist that respect for tradition must not override evidence-based health advice.

“If it gives you energy, then it gives you energy for everything,” one user said — but doctors say that feeling alone is not enough to recommend it as medicine.

Men are therefore advised: consult a qualified health professional first.
