Physical properties

Policosanol is a mixture of a few fatty alcohols derived from the waxes of such plants as sugar cane[1] and yams, as well as beeswax. Fatty alcohols are Aliphatic Alcohols derived from natural Fats and Oils originating in plants but also synthesized in animals and Algae Sugarcane ( Saccharum) is a genus of 6 to 37 species (depending on taxonomic interpretation of tall perennial grasses (family Poaceae tribe Andropogoneae Yam is the common name for some species in the genus Dioscorea (family Dioscoreaceae) For the rock song by Nirvana see Beeswax (song. Beeswax is a natural Wax produced in the bee hive of Honey bees of the genus The most prevalent alcohol in policosanol is octacosanol,[2] followed by triacontanol. 1-Triacontanol is a Fatty alcohol of the general formula C30H62O also known as melissyl alcohol or myricyl alcohol.

There is a much lower concentration of several other fatty alcohols: behenyl alcohol, lignoceryl alcohol, ceryl alcohol, 1-heptacosanol, 1-nonacosanol, 1-dotriacontanol, and geddyl alcohol. Docosanol, also known as behenyl alcohol, is a saturated Fatty alcohol used mainly as an antiviral agent, specifically for treatment of "

Policosanol is marketed by Cuba as a natural way to treat high cholesterol levels. Hypercholesterolemia (literally high blood cholesterol is the presence of high levels of Cholesterol in the blood.

Modulation of HMG-CoA reductase[3] and bile acid absorption inhibition[4] have been proposed as mechanisms. HMG-CoA reductase (or 3-hydroxy-3-methyl-glutaryl-CoA reductase or HMGR) is the rate controlling Enzyme ( of the Mevalonate pathway the Bile acids (also known as bile salts are Steroid Acids found predominantly in the Bile of Mammals.

Studies

Published studies have come to conflicting conclusions regarding the efficacy of policosanol in lowering LDL (i. Efficacy is the capacity to produce a desired size of an effect under Ideal or Optimal conditions Low-density lipoprotein ( LDL) is a type of Lipoprotein that transports Cholesterol and Triglycerides from the Liver to peripheral e. , "bad cholesterol") or raising HDL (i. High-density lipoproteins ( HDL) is one of the 5 major groups of Lipoproteins ( Chylomicrons, VLDL, IDL, LDL, HDL e. , "good cholesterol"). [5][6][7] Despite a number of studies funded by the Cuban government (which also produces and markets the drug), no independent clinical trials have found any evidence of the efficacy of Policosanol.

Production

Policosanol (PPG) is produced, promoted and studied extensively in Cuba, where pharmaceutical research and sugar cane farms both exist in abundance. The Republic of Cuba (ˈkjuːbə or) consists of the island of Cuba (the largest and second-most populous island of the Greater Antilles) Isla de la The supplement is used as a panacea by some Cubans. The panacea (pænəˈsiːə named after the Greek goddess of healing Panacea, was supposed to be a remedy that would cure all Diseases and prolong life indefinitely
