  • Publication number: 20160287651
    Abstract: The present invention relates to a solid preparation including a Pelargonium sidoides extract and a silicic acid compound, which is allowed to be formulated in a solid form by direct adsorption of the Pelargonium sidoides extract onto a silicic acid compound, and a preparation method thereof. Since the solid preparation including the Pelargonium sidoides extract and the silicic acid compound of the present invention has higher stability than a liquid preparation such as syrup, and has no additives such as sugars, there is no concern about microbial contamination or spoilage of the preparation. In addition, it is possible to pack the solid preparation individually. Since the solid preparation is smaller in volume than the liquid preparation, it is highly portable, and there is also a convenience that no additional tools are needed to take the drug. Further, the active ingredient can be taken at the equal amount every time.
