Diabetes mellitus is a global epidemic affecting millions of individuals, particularly in low and middle-income countries. Managing this condition requires sustainable strategies that include traditional and alternative medicine. The plant Boerhaaviadiffusa has been used in Ayurvedic and Homeopathic treatments for various ailments, including diabetes. This study investigates the antidiabetic activity of Boerhaaviadiffusa, specifically in a pilot clinical study conducted on patients with prediabetes. Five cases from the outpatient department of Sarada Krishna Homoeopathic Medical College were selected, and participants were administered Boerhaaviadiffusa Q in a dosage of 10 drops at night over three months. Blood sugar levels were monitored throughout the study using fasting blood sugar (FBS) and HbA1c tests. After three months, a significant reduction in both FBS and HbA1c levels was observed, highlighting the plant's antidiabetic potential. Phytochemical studies reveal that Boerhaaviadiffusa contains bioactive compounds responsible for various therapeutic effects, such as antibacterial, hepatoprotective, anti-inflammatory, and anticancer activities. This manuscript explores the pharmacological properties of Boerhaaviadiffusa, reviews previous studies, and provides clinical evidence supporting its use in diabetes management. The findings of this pilot study suggest that Boerhaaviadiffusa could be a viable option for managing prediabetes and diabetes mellitus in clinical settings, particularly within homeopathic practices.
