The Desert sheep live on natural herbs very rich in the omega 3 fats from which scientists have extracted 700+ medicines. The beneficial oils the sheep absorbed from the herbs are mostly stored in the tail fat.
The prophet (PHUB) said that the fat from the tail should be melted first, and so the harmful bacteria and germs are killed by the heat. It should be taken in three days, not more, to avoid fat oxidation and rancidity. It should be taken on an empty stomach, so that no other lipids compete with the lipids of the tail for absorption in the digestive tract at the vesicule and pancreas level, in addition to the cellular level where enzymes acting at the membrane convert those lipids of the omega 3 group to the beneficial type 3 prostaglandin that reduces inflammation and pain caused by Sciatica.
