title: [Chamomile blooms--a heterogenous drug (manufacture of mixed teas with Matricariae flos)].
abstract: Sieve analyses have proved that the camomile commercial drug is an extremely heterogeneous material which contains ultracoarse particles greater than 4 mm (aprox. 70%) in addition to fine particles less than 0.71 mm (approx. 15%). The ultra-coarse particles are not usable in tea mixtures. For camomile, it is proposed a homogeneous infusion drug (less than 2 mm). The comminution should be performed in the pharmacy. Where species are mixed with camomile, the particle sizes should not exceed 2 mm. The homogeneity of these mixtures is determined by weight comparison of a series of tea-spoon weights. For the comminution of the drugs the authors suggest the use of a "Retsch" cutting mill or a similar appliance which ensures that only few fine particles to be produced. For the removal of suspended fine particles in the infusum of camomile the use of Cilia filter bags is suitable.
