Not only the Argan kernel, but also the pericarp of the Argan fruit is beneficial to help fight diabetes, study demonstrates. Prof. dr. Mohamed Eddouks, dr. Hebi Morad, FST Errachidia, Moulay Ismail University, Morocco published in ‘Cardiovascular & Hematological Agents in Medicinal Chemistry, January 2018.

The pericarp is the tissue that surrounds the kernel.

Pictured: the pericarp of a peach, just like the Argan kernel a stone fruit.

The purpose of this study was to investigate the effect of a single dose and daily oral administration for seven days of aqueous extract of pericarp of Argania spinosa fruit (A.E.P.F.A.S) in normal and streptozotocin (STZ = antibiotic) diabetic rats.

The results:  a reduced blood glucose levels p 6 h after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased in STZ diabetic rats after seven days of treatment. According to the oral glucose tolerance test, the A.E.P.F.A.S. was shown to prevent significantly the increase on blood glucose levels in diabetic treated rats after glucose administration when compared to the control group. Moreover, A.E.P.F.A.S showed antioxidant activity and revealed inhibitory concentration of 50% of free radicals.


This study demonstrates antihyperglycemic, lowering plasma cholesterol levels and antioxidant effects of A.E.P.F.A.S. in severe diabetic state. Further investigations are needed to elucidate the mechanism(s) of action of A.E.P.F.A.S. and the active constituent(s) of the extract.

Argan fruits (the fleshy part) was studied last year by researchers from the German Cancer Research Center, Heidelberg, Germany, and the Team of Physiology, Nutrition and Endocrinology, FST Errachidia, Morocco. Dr. Farid Khallouki et al. summarized a wide range of data on argan fruit botas well as health beneficial effects and examination of future prospects, in particular ethnomedical uses of argan fruits. Argan flesh (pulp) contains a broad spectrum of polyphenolic compounds, of interest to a variety of applications and industries. The study recommends further research, especially on the health beneficial aspects of the aminophenols.

Argan oil extraction press-cake as a source of a natural emulsifier

And if you are here in case of FOMO -:) – Researchers from 4 organizations including. University of Tsukuba, Japan and Cadi Ayyad University, Marrakech, Morocco, studied emulsions with argan press cake. Published in ‘Food Chemistry’, april 2018, we have to understand the impact for our daily life. Looking forward to it! “Formulation and stabilization of oil-in-water nanoemulsions using a saponins rich extract from argan press cake” .  A conference paper was presented at the 18th annual meeting of the Japan Society of Food Engineering.

It is great to learn argan press cake, the pulp that is a left-over after the cold pressing of kernels, is of additional value, other than to use it to feed animals.

Toxicology, #36, 2017. Oils are used in a wide variety of cosmetic products for their skin conditioning, occlusive (= blocking), emollient and moisturizing properties. Since many of these oils are edible, and their systemic toxicity is low, the review focused on potential dermal effects and gave a thumbs up: Safe!
