Many scientific studies have demonstrated the immune-boosting, anti-inflammatory activity, and disease-fighting properties of papaya. Papaya is a major ingredient in our health jelly mix The Pep-Up, designed to provide support to a struggling immune system. We explain the benefits of papaya.

Shiitake mushrooms add a range of minerals and vitamins, especially copper and vitamin B5. These medicinal mushrooms also contain antioxidants, among them the amino acid ergothioneine, the subject of much research as a natural and 'adaptive' antioxidant).

Papaya extracts and papaya-associated phytochemicals possess anti-inflammatory and immunomodulatory properties. Papaya contains a wide range of bioactive secondary metabolites (eg alkaloids, phenolics, flavonoids, carotenoids, tannins, saponins) and proteolytic enzymes (papain and chymopapain). It's also rich in lutein, a type carotenoid.

Astragalus contains astragalans which are polysaccharide constituents that stimulate white blood cells production,T-cells, killer cells and antibodies in a fashion that helps maintain and restore the immune system. 

Medicinal mushrooms are reported to have antimicrobial, anti-inflammatory, cardiovascular-protective, antidiabetic, hepatoprotective, and anticancer properties. It is well-established that mushrooms are adept at immune modulation and affect immature red blood cells, lymphocytes, macrophages, T cells, dendritic cells (DCs), and natural killer (NK) cells. All that medical jargon aside, the bottomline is that both reishi and maitake have been used extensively in cancer treatment in humans and mice.
