A health expert has cautioned against the excessive and prolonged consumption of soursop leaves, warning that misuse could pose serious health risks in spite of their perceived benefits.
Mrs Opeoluwa Aremu, a retired pharmacist and certified health and wellness coach, gave the advice in an interview with the News Agency of Nigeria (NAN) on Thursday in Abuja.
Aremu said that while soursop leaves contain beneficial compounds such as antioxidants and phytochemicals, their effects on human health remain largely unverified, particularly in the treatment of chronic illnesses.
She explained that most of the claims surrounding the medicinal value of soursop leaves were based on laboratory and animal studies, with limited clinical evidence in humans.
“There are promising findings in research, but they are not sufficient to confirm that soursop leaves can treat conditions like cancer, diabetes or infections in humans,” she said.
The expert stressed that excessive intake could be harmful, noting that the same compounds trusted to offer health benefits could become toxic when consumed in large quantities or over a long period.
She warned that prolonged use may affect the nervous system, lower blood pressure beyond safe levels, and in some cases lead to symptoms associated with neurological disorders.
“Soursop leaves can be beneficial if used cautiously, but overuse can damage the nerves and affect the body negatively. It is not something that should be taken continuously for a long time,” she said.
Aremu also highlighted the lack of standard dosage in the preparation of herbal remedies, noting that individuals often consume varying quantities without proper guidance.
“Unlike conventional medicines, there is no approved dosage. People prepare it differently, some boil large quantities, others even juice it, which increases the risk of overconsumption,” she said.
She discouraged the practice of juicing soursop leaves, explaining that it could lead to higher concentrations of active compounds and increase the likelihood of toxicity.
The expert further noted that soursop leaves could interact with medications, especially for individuals managing conditions such as hypertension and diabetes.
“If combined with blood pressure or diabetes medication, it may lead to dangerously low levels. That is why people must consult their doctors before using it,” she said.
According to her, certain groups, including pregnant and breastfeeding women, as well as individuals with neurological conditions, should avoid consuming soursop leaves.
Aremu attributed the growing use of herbal remedies to rising healthcare costs, side effects associated with conventional drugs, and misinformation on social media.
She emphasised the need for increased awareness and scientific research to properly regulate the use of herbal products.
“People should understand that because something is natural does not automatically make it safe. Some natural substances can be harmful if not properly used,” she said.
She advised Nigerians to prioritise balanced diets and seek professional medical guidance before adopting herbal treatments. (NAN
