Acemannan is a D-isomer mucopolysaccharide found in aloe vera leaves.

This compound has been known to have immunostimulant, antiviral, antineoplastic and gastrointestinal properties[1].

In dogs, it has been used for treatment of chronic viral infections and cancers such as osteosarcoma, melanoma, lymphosarcoma and fibrosarcomas in combination with surgery and radiation therapy[2][3].

Recommended dose rate in dogs is 1 - 2 mg/kg given intralesionally, intraperitoneally or subcutaneously once a week[4].
