History: Khaya Senegalensis
Khaya senegalensis is an invaluable source of potent medicines, with its use being traced back as far as 1000AD .
It is now extremely rare, largely due to land clearing practices. It was listed as vulnerable on the International Union for Conservation of Nature and Natural resources (IUCN) Red List of Threatened Species over 20 years ago. Since then land clearing in Africa has intensified, almost wiping out the species completely in the wild .
Australia, thanks to the research efforts of the Australian Federal Government research agency CSIRO and state governments’ departments of agriculture since the 1960’s, Australia is now the largest grower of pristine medicinal-grade Khaya senegalensis in the world.

Polyphenol Chemical Profile – Antioxidants, Anti-inflammatories and Pre-biotics
The evidence for Khaya senegalensis, traditional and scientific, points to a botanical that eliminates ‘bad’ bacteria (2-5,12,23) and fosters an environment where ‘good’ bacteria can thrive. It does this by providing protective anti-inflammatory and extremely high antioxidant activity (3,9) together with ‘good’ gut bacteria food in the form of pre-biotic polysaccharides. All provided within its diverse polyphenol-rich chemical profile (22).

Menstruation Mechanisms & Abdominal Disorders – Significant Anti-Inflammatory and Analgesic Effects
Khaya senegalensis through both cellular and animal studies investigating extracts of bark has demonstrated that oral and topical administration results in significant anti-inflammatory and analgesic effects. Anti-inflammatory activity was demonstrated to be significant in the inhibition of cyclooxygenase (COX) enzymes, in particular COX-2 (9,18). Khaya senegalensis has also been shown to inhibit inflammatory pathways mediated by Free Radical ABTS, Caspase 3, AKT1, MAPK3 and EGF receptors (9,18). Studies of the aqueous bark extract have also demonstrated significant antinociceptive activity and suggest that this effect is mediated, both centrally and peripherally, through stimulation of opioid receptors (3,8).
