TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The multiple microbes utilized are preferably lactic acid bacillus, more preferably Lactobacillus plantarum and the Torula yeast Candida utilis and a sulfurous acid especially potassium metabisulfite (K2S2O8) is added and used in the case of fermentation. ACTIVITY - Analgesic; Dermatological; Antiarthritic.    No suitable data given.    MECHANISM OF ACTION - None given.    EXAMPLE - About 5 cms of the roots of a ground portion stalk, about 10 cms were left and cut off and harvest was gathered. The gathered material was immediately fed into a washing tank, and was dehydrated, and them was cut to about 50 cm or more preferably 60 cm. Then, it was fermented by throwing in to pH:4, 5 which contained a lactic acid Bacillus , where the fermentation was carried out at a fermentation temperature 37degreesC, where it was combined with the fermentation by this lactic acid Bacillus and prevention of various microorganisms contamination was aimed at by the reduction of pH value by continuous addition of a sulfurous acid, and the fermentation of starting material was also accelerated by the reduction of this pH value more than at estimation. Moreover forming of components, such as the bitterness further contained in a starting material was completely controlled by addition of this sulfurous acid. This fermentation had a logarithmic growth phase, where the starting material was collected next when the fermenter set as pH 3, 5 at a fermentation temperature of 15degreesC in order that the collected starting material might perform re-fermentation with Torula yeast, throwing in fermentation performing the time of front fermentation being similar a logarithmic growth phase, with it makes as the final period of fermentation, and it controlled and the starting material was collected. After it threw the collected starting material into the distillation tank and the normal pressure-type extractor extracted it after distillation, the refiner refined it. Moreover, extracting residuum of a starting material was refined, after having dried by normal temperature ventilation as it was in the extractor and a fine powder was made.
