GRETHA in French, means a team of researchers working on therapeutic effects of argan oil. The team includes researchers in several medical areas (nephrology, rheumatology, neurology, ophthalmology, endocrinology and pharmacology) from the faculty of medicine of Fez (University Sidi Mohamed Ben Abdellah) and Rabat (University Mohamed V), and their corresponding university hospitals, Hassan II and Mohamed V’s Instruction Military Hospital, respectively. GRETHA is extending its framework and recently, other collegues have joined the team from the university of Sevilla (Faculty of Pharmacy) and the university of Valencia (Faculty of medicine and Faculty of pharmacy) in Spain. The main research work on argan oil is performed as clinical trials, though, basic research on tissue cell cultures are used. In recent studies, argan oil consumption has proved to be a good tool to manage dyslipidemia in patients, through improving HDLc, LDLc, TGs, lipoprotein A and lipoprotein B levels. Argan oil consumption also proved to provide joint pain relief in osteoarthritis patients. The special chemical composition of argan oil (polyphenols, tocopherols, mono and polyunsaturated fatty acids, sterols) is a key factor for its anti-oxidant and lipid-lowering properties, which may explain its health benefit properties in several health conditions, such as cardiovascular events, neurodegenerative events and memory loss, retina issues and macular degeneration, male subfertility and other health issues.
