Research on formulation of hard capsules containing extracts of Houttuynia cordata thumb (Saururaceae), Morus alba l. (Moraceae), and Carica papaya l. (Caricaceae)

The research focuses on the composition of a hard capsule formula containing the extracts of Houttuynia cordata, Morus alba, and Carica papaya as well as the development of testing standards for prepared hard capsules. Materials and methods: the ratio of adsorbents and fillers in the formula was investigated so that the granules had low moisture, a suitable flow rate, and the appropriate apparent density for packaging.
