The objectives of this study were to form comparisons of total polyphenol compounds, the antioxidant activities and the urushiol contents of lacquer tree(Rhus verniciflua) bark and the sensory properties of chicken soup was made with lacquer tree bark that was cultivated from different cultivation areas; Hamyang, Wonju and China. Total polyphenol contents of Hamyang, Wonju and China were estimated as $375.28{\pm}3.48$, $403.60{\pm}6.6$ and $311.06{\pm}4.99$ mg/g. The total flavonoids contents of Hamyang, Wonju and China were measured as $374{\pm}14.12$, $683.70{\pm}12.64$ and $334.64{\pm}18.40$ mg/g. The total phenolic compounds and flavonoids concentration, DPPH radical scavenging activity, and ABTS radical scavenging of lacquer tree cultivated in Wonju were higher than the others; Hamyang and China. The urushiol content of lacquer tree bark from Hamyang was $4.59{\pm}0.04$ ppm and higher than others. Urushiol was not detected in China lacquer tree bark. Sensory evaluation tests for chicken soup containing lacquer tree bark showed that the scores of Wonju lacquer tree bark chicken soup was highest, however there are no differences between Hamyang, Wonju, and China significantly(p<0.05).

Objective : The purpose of this study is to report a case of lacquer allergy improved by Korean medicine treatment. Methods : The patient visited our hospital complaining of rash, and pruritus which lasted for 10days after eating lacquer chicken. Considering that patient's symptoms occurred due to food allergen, we prescribed Injinho-tang(Yinchenhao-tang) and acupuncture at Daejang-Junggyeok for 7days. Results : On the 4th day of treatment, pruritus decreased to less than half of the initial treatment, and skin symptoms also improved to a mild level. About a week later, most of the skin symptoms disappeared (Total Objective Symptom score decreased 10 to 3), and subjective symptoms such as pruritus improved to about 30% of the time of the first visit (Total Subjective Symptom score decreased 12 to 3). Conclusions : After 7days of Korean medicine treatment, lacquer tree allergy with skin lesions and pruritus has improved considerably.

Objectives: This study reports using Hyungbangsabaksan to cure Soyangin Yangdokbalban (陽毒發斑) appealing Systemic Allergic Contact Dermatitis. Methods: After diagnosing the patient showing Papuloerythematous with no blisters in the body as a Soyangin Yangdokbalban (陽毒發斑), we prescribed the patient with Hyungbangsabak-san. We compared the condition of the patient before and after medication with photo shots. Results: After treatment, Papuloerythematous which was seen with the naked eye disappeared and various skin symptoms such as itching and warmth in the flare area also improved. Conclusions: After treatment, the symptoms of the patient who after eating lacquer chicken showed improvement.

In Korea, for a long time Rhus verniciflua has traditionally been used as an herbal medicines plants. A stem of Rhus verniciflua has been used to treat gastrointestinal trouble with in form of boiled chicken as a folk medicine. But it has been recognized as an extremely active allergen causing skin reactions. The chief allergenic component, urushiol, is found within the oleoresinous sap of Rhus verniciflua. Most components of urushiol have unsaturated side chains. These unsaturated side chains of urushiol are important to polymerization of these natural products. The urushiol components in Korean lacquer were isolated by reversed phase HPLC. The molecular weight of purified urushiol was determined as 340 from mass analysis. This compound was identified as Heptadecatetraenyl catechol (MW 340).
