A deep dive of the research on Acemannan

Acemannan was identified in the 1980’s and Carrington Laboratories became one of the major organizations developing it as a medical ingredient. They named it “Carrisyn”. Acemannan itself can’t be patented, but they patented the specific acemannan extraction methods, and medical uses. Patents don’t mean the product itself is safe or effective, it just gives us a clue that there was potential for it to be commercialized.
