Multi-Gyn FloraPlus. FloraPlus contains 40% 2QR, which regulates the pH balance, making the vagina more acidic and creates a protective barrier against harmful microbes and bacteria. It also contains selective prebiotics, which nourish the good bacteria which release lactic acid, to naturally maintain the slightly acidic pH of a healthy vagina, and prevents thrush from getting out of control again.
