Herbal medicines have been used worldwide, particularly in the Far East countries, for thousands of years. Herbal medicines comprise complex mixtures of different phytochemical substances, and their nature may vary substantially depending on many factors related to the cultivation condition, area and harvest time. The processing of the herbal medicines significantly affects their pharmacological and toxicological properties. In this paper, we discuss current research that deals with the techniques for processing Chinese herbal medicines. These results will provide a scientific basis for developing new techniques for the processing of herbal medicines.

We compared with heavy metal concentration of herbal medicines in products of Gyeongbuk and the other area of Korea. The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Gyeongbuk area. The average levels of heavy metal of herbal medicines in Gyeongbuk area are as follows : Mercury is 0.037mg/kg, Chromium is 0.093mg/kg, Nickel is 0.108mg/kg, Copper is 0.475mg/kg, Zinc is 3.14mg/kg, Manganese is 1.52mg/kg, Iron is 7.83mg/kg, and Cadmium, Lead and Arsenic is not detected. It was very lower in concentrations than those of average Korea area. Therefore, Gyeongbuk area appear to be more proper to cultivated land than other area.. Minerals such as Ca and K were extracted more than Na and P in herbal medicines products of Gyeongbuk respectively. Minerals and heavy metal concentrations distributed in herbal medicines were analyzed. Little or no relationship was observed between minerals and heavy metals.

This study was conducted to determine the contents of heavy metal in commercial herbal medicines. The monitoring of lead, arsenic, cadmium and mercury was carried out on 100 samples with 10 kinds of herbal medicines. The contents of heavy metal were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) and mercury analyzer. The mean values of heavy metal contents for herbal medicines were Pb 1.87 mg/kg, As 0.39 mg/kg, Cd 0.26 mg/kg and Hg 0.021 mg/kg. Of the total samples, 19 samples (19%, 4 types) were violated the KFDA regulatory guidance of heavy metal in herbal medicines (9 samples on Pb, 10 samples on Cd). Among these 19 unsuitable samples, 16 samples were domestic and 3 samples were imported. Therefore, we need continuously monitoring to ensure confidence and safety for these herbal medicines.
