Cathay was born in the U.S.A. and her American father bought her up on Indian folklore Medicine and where possible in her childhood, avoided antibiotics and expounded the use of healthy food and lifestyle. Her Maternal Grandmother who lived with them was Greek and taught the family the healthy Mediterranean way with plenty of olive oil, fresh vegetables and red wine. Cathay’s family moved to Australia where she went to school and grew up with the Aboriginal folklore and bushman knowledge of survival with the use of plant medicine in the outback and of course the dreamtime and walkabout stories. After Australia they moved to Papua New Guinea where again traditional folklore and knowledge of the fruit and herbs were used for medicines.

"rainforest plants - ancient remedies" 

Specialising in Aromatherapy and therapeutic massage rehabilitation, Cathay moved to Jordan. Here she had the extraordinary experience and privilege to work with members of the Royal Family who encouraged her to learn more complimentary therapies thereby adding to her already vast knowledge and experience.

Rob grew up in the countryside on a virtually self sufficient organic farm which his parents ran as close to nature as possible. He learned from a young age that nature knew best. He first trained as a herbalist using natures plants to maintain health, gaining a background in Homeopathy he moved in to the science of Iridology (body system analysis through the iris) practising at an intermediate level. He also had the useful experience of a paediatrician from a local hospital interested in his work, who referred two children with chronic constipation and digestive problems to him. Using Kombucha therapy and plant medicine and under the watchful eye of the consultant, these childrens health conditions improved, re-emphasizing the power of natural medicine. Using Kombucha based preparations as the foremost basis of health treatment, they have proven themselves to be capable of helping regain health countless times ever since.
