"Previous studies have indicated that Bromelain removes the spike and hemagglutinin proteins of Semliki Forest virus, Sindbis virus, mouse gastrointestinal coronavirus, hemagglutinating encephalomyelitis virus, and H1N1 influenza viruses [15,16]."

"In vitro studies show that bromelain can tear apart the outer protective envelope of certain viruses like HIV, HPV and Hepatitis C.[8]
With the outer layer damaged, “the virus had either lost its capability to reproduce or was destroyed altogether.”"

"As this viral envelope was damaged buy the proteolytic acitivies, the virus had either lost its capability to reproduce or was destroyed altogether, since, the viral outer layer was damaged. These positive effects of bromelain activities towards these viruses have been shown in-vitro in our lab. Bromelain enzyme originating from the flesh and the stem of pineapple fruit has been shown to have the potential to be utilized as antiviral agent againstviral borne diseases which include HIV/AIDS, Hepatitis C and HPV that could cause cervical cancer."

"Based on the improvement of the patient's condition, fresh pineapple juice has the potential as an alternative pathway for the cure of HIV/AIDS."
