Policosanol is the generic term for a mixture of long chain alcohols extracted from plant waxes.

Policosanol was originally derived from sugar cane but the chemicals can also be isolated from beeswax, cereal grains, grasses, leaves, fruits, nuts, and seeds of many foods.

[1] A meta-analysis in 2005 concluded that human policosanol consumption is safe and well tolerated and is effective at lowering the blood cholesterol.

[1] Furthermore, another meta-analysis published in 2018 with 22 studies and 1886 subjects showed policosanol could improve dyslipidemia with raising HDL.

[4] The blood pressure lowering effect of Cuban policosanol has been shown in an animal model using spontaneously hypertensive rats (SHR)[5] and a human trial.
