Biography

Dr Kristian Leisegang is a senior lecturer and currently the Acting Director of the School of Natural Medicine (SoNM), University of the Western Cape (UWC). He obtained a M.Tech.Hom on 2007 from Durban University of Technology, and a PhD (MBS) in 2014 from UWC. He is a registered homeopathic practitioner with the Allied Health Professions Council of South Africa, Department of Health, which has included clinical practice experience. As the coordinator of the clinical science training modules at SoNM, his teaching focus includes pathology, general medicine and clinical diagnostics, alongside research methodology, to undergraduate and postgraduate students. Postgraduate supervision includes a completed MSc student supervision, with ongoing MSc and a PhD projects. This research focuses is on obesity, metabolic syndrome and related phenomenon such as insulin resistance, chronic inflammation and oxidative stress within the context of male (patho) physiology and reproductive (dys)function. This extends to investigating various nutritional supplements, antioxidants and medicinal herbs as novel treatment strategies within this context.

Kristian has currently published numerous articles and book chapters in accredited, peer reviewed international journals and publications, and presented more than 17 oral and poster presentations at national or international scientific meetings, as well as been recognised with institutional and international awards. This is also reflected in a peer review expert for more than 20 international accredited journals.

Biography

James Campbell completed a four year diploma in phytotherapy obtained from the College of Phytotherapy (then affiliated to the University of Wales), United Kingdom, which formed the basis of a passion for medicinal plants. He completed his MSc (Cum Laude) through the South African Herbal Science and Medicine Institute (SAHSMI), Faculty of Natural Sciences at the University of the Western Cape (UWC) and is currently busy with a PhD through the Department of Biotechnology, Faculty of Natural Sciences, UWC.

The topic for his master’s was “The impact of storage time and seasonal harvesting on biomarker levels of Lessertia frutescens” and at present he is investigating the impact climate change has on medicinal plants for his PhD studies.

He has been the Director of the School of Natural Medicine (SoNM) for ten years, as well as the co-ordinator of the phytotherapy programme since 2009. Having recently stepped down from the directorship to focus on professional and personal development, he remains the co-ordinator of the phytotherapy programme for the school. Balancing leadership of the school, the phytotherapy programme, full time lecturing and supervising at the clinics, serving on the Allied Health Professions Council of South Africa (AHPCSA), with private practice has been an enlightening, life changing and rewarding experience.

Hands down his favourite subject is materia medica, taught to the B Complementary Medicines (Phytotherapy) fourth and fifth year students, more recently becoming the lecturer for herbal medicine to the naturopathic fourth year students as well. Other focus areas are herbal pharmacology, herbal nutrition, preventative medicine, diet and lifestyle, environmental influences on plants and their constituents, as well as energetics. The ‘bigger picture’, the philosophy of the ‘whole is greater than the sum of its parts’ and wisdom from a diversity of ancestors - how does it all tie in to our physical, mental and spiritual well-being.
