You will leave the session with a nutrition plan, insight into your emotional landscape (where that is necessary) and herbal medicine if / when necessary.

Jenny gets great results with her clients as a very happy lady wrote to us recently. This is truly why we do what we do! Nothing gives us greater joy than witnessing a shift in someone’s health. Jenny is a superstar within the Dr Libby Team. We are very blessed to have her as part of our team.

Client Testimonial :

For years I have suffered from PMT …. severe mood swings, low energy, erratic angry outbursts, sadness, depression and a daily roller coaster of emotions. With my marriage hanging by a string and two small children unsure of which ‘mum’ they would get today… Someone suggested my hormones may be out of balance and to see Jenny at Dr Libbys office. After 2 weeks of being on the herbs Jenny gave me I felt calmer, more balanced and more energetic. After 2 months it has completely changed my life. I literally feel like a different person. I can regulate my own emotions, I can deal with the stress of daily life, I am happier, balanced and in control of my life and have a heap of energy. My kids are more settled and well behaved and my husband and I are more in love than we have been. Thank you Jenny!!!! You changed my world!!!
