Hibiscus tea good for health – UNILORIN don
By Abubakar Abdulquadri
A lecturer in the Department of Health Promotion and Environmental Health Education, University of Ilorin, Dr Jamiu AbdulQudus Tosin, has canvassed the consumption of hibiscus tea, popularly known as zobo, for its health benefits.
Dr Jamiu, who made this recommendation following a research study titled “Perceived Influence of Hibiscus -Tea (Zobo) Intake on Wellbeing of Residents in Ilorin West Local Government Area of Kwara State, highlighted the potential of hibiscus tea in promoting healthy living.
According to the findings, regular consumption of the beverage may help lower high blood pressure, reduce body weight, increase good cholesterol levels, and inhibit the growth of cancerous cells.
Speaking with UNILORIN Bulletin last Tuesday (March 24, 2026), Dr Jamiu explained that hibiscus tea is a widely consumed drink across Africa, especially in Nigeria, where it is enjoyed by both adults and young people.
He noted, however, that despite its popularity, many consumers remain unaware of its numerous health benefits and the simplicity of its preparation process.
“Hibiscus tea, commonly known as zobo, offers significant health advantages when properly prepared and consumed, particularly when served chilled,” he said.
He further described hibiscus tea as ‘‘a herbal infusion made from the crimson-colored calyces of the roselle plant (Hibiscus sabdariffa). The drink can be consumed either hot or cold and is known for its tart, cranberry-like flavour’’.
The researcher emphasised that ‘‘the quality of zobo largely depends on the physio-chemical properties of the raw materials used, the quality of water, and the hygiene practices observed during preparation’’.
He explained that ‘‘water, being a major component in production, must meet safety standards, as poor-quality water containing harmful chemicals, heavy metals, or microbial contaminants—can significantly affect the safety and quality of the drink’’.
Dr Jamiu also cautioned that certain preparations of hibiscus tea may contain mild hallucinogenic properties, particularly depending on the additives used. As a result, he advised that such variants should be avoided by drivers, factory workers, and individuals engaged in tasks requiring high levels of concentration to prevent drowsiness or impaired alertness.
He reiterated the need for proper awareness and safe preparation practices to fully harness the health benefits of the popular local beverage.
