Main Preparations used:

History
'This drug under the name of Mahmira is used in Sind for inflammation of the eyes, a circumstance which enabled Pereira to identify it with a substance bearing a nearly similar designation, mentioned by the early writers on medicine, and previously regarded as the root of Chelidonium majus L.

Thus we find that Paulus Aegineta in the 7th century was acquainted with a knotty root named Mauripas. Rhazes, who according to Choulant died in A.D. 923 or 932, mentions Mamiran, and it is also noticed by Avicenna a little later as a drug useful in diseases of the eye. Mauripas likewise occurs in exactly the same way in the writings of Leo, "Philosophus et Medicus." Ibn Baytar called the drug Mamiran and Uruk, and described it as a small yellow root like turmeric, coming from China.

Other writers of the middle ages allude to it under the name of Memeren. Hajji Mahomed, in the account of Cathay which he gave to Ramusio (circa, A.D. 1550) says that the Mambroni chini, by which we understand the
root in question, is found in the mountains of Succuir (Suh-cheu) where rhubarb grows, and that it is a wonderful remedy for diseases of the eye. In an official report published at Lahore in 1862,* Mamiran-i-chini is said to be brought from China to Yarkand.

The rhizome of Coptis is used by the Chinese under the names Hwang-lien and Chuen-lien. It is enumerated by Cleyer (1682) as "radix pretiosa amara," and was described in 1778 by Bergius who received it from Canton.

More recently it was the subject of an interesting notice by Guibourt who thought it to be derived from Opkioxylon serpentinum L., an apocyneous plant widely removed from Coptis. Its root was recommended in India by Maclsaac in 1827 and has been subsequently employed with success by many practitioners. There is a rude figure of the plant in the Chinese herbal Pen-tsao.'
