Abstract
Pereskia bleo is a leafy cactus traditionally used for various purposes. We aim to study the information about the usage, preparation methods, effects and possible unwanted effects of Pereskia bleo from the users of fresh medicinal plants in Singapore. The participants were recruited through advertisement and interviewed. Data was evaluated using thematic analysis and statistical methods. From 25 participants, 36% used this plant for treatment of medical conditions such as breast, lung and prostate cancers and constipation, 32% for health promotion like detoxification and improving blood flow and immunity, and 32% for both. Reported side effects were mild and reversible pruritus, diarrhea, cold sensation and weakness in the feet, and increased prothrombin time caused by potential herb-drug interaction. Studies are needed to further explore the potential therapeutic effects and possible herb-drug interactions. Moreover, healthcare professionals should actively enquire about the concurrent usage of fresh medicinal plants including Pereskia bleo by patients to monitor for possible interactions.
