Our product contains the mushroom extract Yunzhi PSP, which has been known to boost immune health and has recently been clinically proven to be an effective anti-cancer supplement for dogs.




Yunzhi, also known as Coriolus Versicolor or Turkey Tail, is a type of mushroom commonly used in Traditional Chinese Medicine. The active ingredient is Polysaccharopeptide (PSP), and it is believed by researchers to have immune-boosting properties, and, more recently, tumour-fighting abilities. In a 2012 study by the University of Pennsylvania School of Veterinary Medicine, researchers found that dogs treated with PSP daily had a survival time of almost 200 days, compared to the average of 86 days without any treatment. 



“We were shocked. Prior to this, the longest reported median survival time of dogs with hemangiosarcoma of the spleen that underwent no further treatment was 86 days. We had dogs that lived beyond a year with nothing other than this mushroom as treatment".
