Bromelain is a mixture of enzymes found naturally in the juice and stems of the pineapple plant. For inflammation, allergies, heart health, allergies, thrombosis (blood clotting) & cancer. It is a cysteine protease. The flesh has trace amounts, juicing has higher concentrations & the highest source is in the stem. This can be extracted yourself with a juicer & cheesecloth (else supplementing is an option). Bromelain = healthy ‘blood vessels & heart’ & antiviral against coronaviruses.
