In a study carried out on healthy women and postmenopausal women, it was seen that oral supplementation containing 50mg rosehip, 200mg of both L-arginine and L-citrulline along with 20mg Pycnogenol, increased their libido as indicated by Female Sexual Function Index (FSFI), in a period of 8 weeks. However, more research needs to be done to establish rosehip as an active component that may increase libido. [52]
