The earliest record of extracting sex hormones
The northern cooldown years, in "the great scientists ShenKuo ShenCun recipe recorded in the autumn of stone" and the preparation methods, this shows that our refined in 11th century, or more early some can already extracted from human urine fairly pure sex hormones preparations. This is the earliest record of sex hormones about extraction.
Specific refining method: "(YangLian law), regardless of how many urine for about two tong, a bear with clear water first pick good soap Angle pus, Zi stranded with cloth, each to urinate a barrel, soap Angle juice a lamp that, in a bamboo grate urgent stirred. By turns to turn the syndrome is BaiZhuo urine to clarify, until the end, but both anchorage who skimmed slowly, only without clear feet, and take turbidity, and with a bucketful of bamboo BiZi stir, the more wait to clarify, who only skim qing without, ten feet, but bear has strong twos juice, its a shall is first to cloth filtration, don't make a Zi, obtains the concentrated juice, into the net pot Fried dry, scraping down dolly, again into the pot, cooked with clear soup, but in ShaoJi inside, party next clear juice, and pour into the pot boil dry" finally obtain color as white as the "autumn frost stone". "Autumn stone" is used in the treatment of prolonged illness cough and asthma, dizziness, emaciated etc, have very good effect.
The above process is after using saponins precipitation, filtration, heating, concentration, sublimation, heavy crystallization and so on a series of physical and chemical methods, propose a sex hormones preparation methods. In western medicine, 1927 found that pregnant women urine contains a lot of sex hormones, later again in 1932 from human urine to the pure sex steroidal shock is isolated. And in the motherland medicine, nine hundred years ago from human urine is realized by extracting quite pure sex hormones preparation of this great invention. Needham, etc ShenKuo making "autumn people praise stone", "is undoubtedly modern science, any type of science before an extraordinary achievement medicine."
