Patent ID: 7374784

Claim:
A method for producing tablets from plant extracts, the method comprising the steps of: a) mixing highly dispersed silicon dioxide with a dry plant extract to produce a mixture of silicon dioxide and the dry plant extract; b) mechanically pressing the mixture: c) passing the mixture through a sieve to produce compacted extract particles where at least 99% of the particles are smaller than 1,000 μm, at least 90% of the particles are smaller than 710 μm, 40% to 80% of the particles are smaller than 500 μm, 30% to 60% of the particles are smaller than 250 μm and a maximum of 40% of the particles are smaller than 125 μm d) covering the compacted extract particles with moisture-protecting adjuvants; e) adding to the compacted extract particles a combination of at least three disintegrants, wherein the combination comprises between 5% and 15% by total weight of the compacted extract particles sodium hydrogencarbonate; and f) pressing the particles of step (e) into tablets by a tablet press.
