It contains a wealth of information of biological functions. In this paper, single photon counting system is used to measure UPE of some anti- cancer herbal plants. For the plants, the changes of UPE under different water condition are stud-ied and the varying laws of ultraweak photon number with time are analysed. The results are higher fit double exponential decay law. %K Ultraweak Photon Emission %K Photon Counting %K Barbed Skullcap Herb %K Pedate Pinallia Jackinthepulpit Rhizome %K Cochinchnese Asparagus Root %K Fitting %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=433
