杜仲为常用中药之一,其炮制方法较多,历代本草载有“酥炙”、“麸炒”、“盐水润后蒸”、“炒令黑”等法。《中华人民共和国药典》1990年版规定为“盐炙”,即“取杜仲块加盐水拌匀、润透,用中火炒至焦黑色,易断丝时取出放凉”。我们经过多次试验对比,发现“盐润砂炒”法最佳,现介绍如下。 Eucommia is one of the commonly used traditional Chinese medicines, and its preparation methods are many. Herbal medicine has been contained in ancient dynasties such as “puff pastry”, “fried bran”, “saline steamed and steamed”, and “fried black”. The 1990 edition of the “Pharmacopoeia of the People’s Republic of China” stipulates “salt cake”, which means “take a mix of eucommia bark and salt water, mix thoroughly, run through it, stir fry black in medium heat, and take out and let cool when broken.” After several trials and comparisons, we found that the “Salt Runchao Method” method is the best and is described below.
