Abstract: A process for preventing precipitates in fresh pressed echinacea plant juice comprising cooling the fresh pressed plant juice obtained for a short time, followed by filtration and stabilisation by the addition of acid. The pressed plant juice is preferably cooled to temperatures between 0 and -15.degree. C. for less than 14 days and after filtration adjusted to a pH value below 6 by adding 0.01 to 5% of a polyvalent carboxylic acid, preferably citric acid.
