For the purpose of developing Korean Herbalogy with the plants of Polygonaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigative and the results obtained were as follows: 1. According to nature and flavour of medicinal plants, they were classified into cold, cool; 23 each, warmth, heat; 11 each, balance 11 and unidentified 5. Thus it was noticed that cold, cool is the main in nature and flavour of medicinal plants. 2. According to the Properties and Principal curative action, they were classified into drugs for clearing up heat and toxin 18, drugs for regulating the fellow of Gi to alleviate pain 14, drugs for removing heat from the blood to stop bleeding 13, drugs for expelling wind and removing dempness 11, drugs for parasiticide 11, drugs for promoting blood circulation to remove blood stasis 10, drugs for strengthening the spleen and stomach 10, drugs for inducing diuresis to alleviate edema 9, drugs for improving acuity of vision 5 and drugs for tonifying and nourishing 4. Thus it was noticed that durgs for clearing up heat and toxin was the main kind. 3. Comparing to whole medicinal plants 47 kinds, toxic durgs include minor toxin were 12 kinds, 25% of the whole. Thus toxic durgs were slightly poisonous. From this result, it was revealed that the plants for medical purpose in Polygonaceae was 30% of the whole, in which drugs for clearong up heat and toxin was mostly abundunt and toxic plants was slightly poisonous. It is considered that many experiements and clinical approaches must be continued widely about slightly poisonous drugs.

We studied biblographically on the origin of Zitanxiang which is commonly used at Oriental Traditional and Herbal Drugs Clinic. Results are as follows. We can find out that ; 1. In China, Pterocarpus indicus Wild. and Pterocapus santalinus L. which are duramen of woody parts of the plants of Leguminosae are used as Zitanxiang medicinal stuff. 2. In Korea, Sabina chinensis(L) Antoin (= Juniperus chinensis L.) which is the woody parts of Chinese cypress which is evergreen arbor and one of the plants of Cupressaceae is used as Zitanxiang medicinal stuff. Therefor, it is thought that comparison research have to be studied on these different Zitanxiang medicinal stuffs on the basis of efficacy.

For the purpose of developing Korean Herbalogy with the plants of Polygonaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigative and the results obtained were as follows: 1.There were totaled to 16 genera and 156 species in Korea and among them medicinal plants are 12 genera, 47 species, some 30% in total, but the number of species may be added because of the similiar plants. 2.According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Polygonaceae family were classified as Herba 21, Radix 12, Foilum 8, Lignum 5, Flos 4, Fructus 5, Ramulus 2 and Semen 1. Thus it was noticed that Herba was the main kind. 3.According to sum of 156 species in Polygonaceae family, they were classified into Persicaria genera 63, Polygonum genera 23, Rumex genera 22, Bistorta genera 14, Aconogonum genera 6, Fagopyrum genera 5, Bilderdykia genera 4, Amblygonum genera 3, Reynoutria genera 3, Rheum genera 3, Pleuropterus genera 2, Pleuropteropyrum genera 2, Tovara genera 2, Ampelygonum genera 1, Homalocladium genera 1 and Oxyria genera 1. Thus it was noticed that Persicaria genera was the main kind, some 40.3% in total. 4.According to nature and flavour of medicinal plants, they were classified into cold, cool; 23 each, warmth, heat; 11 each, balance 11 and unidentified 5. Thus it was noticed that cold, cool is the main in nature and flavour of medicinal plants. From this result, it was revealed that the plants for medical purpose in Polygonaceae was 30% of the whole, in which HERBA was mostly abundunt and toxic plants was slightly poisonous that it will be used for clinical treatments more easily. It is considered that many experiements and clinical approaches must be continued to use Polygonaceae plants widely.
