Fish oil supplements questioned

These pills are often seen as a way to increase heart-healthy omega-3 fatty acids, but this might not be the case, according to a recent study from UBC. In a study conducted on mice, UBC assistant professor of biology Sanjoy Ghosh found that mice which were already eating a diet including vegetable oil actually has less ability to repair cells in their gastrointestinal system when they were fed fish-oil supplements as well.
“Our hypothesis is that levels of omega 6 [fats found in vegetable-based oils] are so high in our bodies that any more unsaturated fatty acid — even omega 3, despite its health benefits — will actually contribute to the negative effects omega 6 PUFA have on the heart and gut,”  Ghosh told The Vancouver Sun. “When there is too much [polyunsaturated fatty acid], the body doesn’t know what to do with it.”

Ghosh’s work was published in the British Journal of Nutrition.

Pharmacy History

"The earliest known compilation of medicinal substances was ARIANA the Sushruta Samhita, an Indian Ayurvedic treatise attributed to Sushruta in the 6th century BC. However, the earliest text as preserved dates to the 3rd or 4th century AD.
Many Sumerian (late 6th millennium BC - early 2nd millennium BC) cuneiform clay tablets record prescriptions for medicine.[3]

Ancient Egyptian pharmacological knowledge was recorded in various papyri such as the Ebers Papyrus of 1550 BC, and the Edwin Smith Papyrus of the 16th century BC.

The earliest known Chinese manual on materia medica is the Shennong Bencao Jing (The Divine Farmer's Herb-Root Classic), dating back to the 1st century AD. It was compiled during the Han dynasty and was attributed to the mythical Shennong. Earlier literature included lists of prescriptions for specific ailments, exemplified by a manuscript "Recipes for 52 Ailments", found in the Mawangdui tomb, sealed in 168 BC. Further details on Chinese pharmacy can be found in the Pharmacy in China article."
