Dose-Ranging Study of SKF7® for Obesity

Labisia pumila or Kacip Fatimah, a native Malaysian plant, has been used as traditional medicine for over 400 years by both men and women for multiple treatments. Studies in animal models showed that Labisia pumila extract could regulate body weight gain and visceral fat reduction. SKF7® is a standardized extract of Labisia pumila (Kacip Fatimah) from the Myrsinaceae family.
