Sutherlandia frutescens is a scrubby little bush, fond of the most arid regions of southern Africa. What makes this plant extraordinary is the way in which African tribes have used the leaves for centuries to treat cancer, ulcers, anxiety, flu and arthritis.
When scientists took this plant into the laboratory they found it to have anti-inflammatory, anti-viral and anti-fungal properties. It also (quite famously) stops wasting in cancer patients.
The next question to answer was how this plant had these effects. Sutherlandia frutescens, when analysed, was found to contain L-canavanine, pinitol, GABA (gamma aminobutyric acid) and asparagine.
Amongst other therapeutic effects, the leaves are anti-inflammatory, antioxidant and immuno-modulating. It also seems to be very safe and well tolerated.
This is exactly what is needed to alleviate your pet’s itchiness and that is why we have included this herb in our Itch (Allergy) Formula.
