... How can I, and if possible smother the ginseng powder? ... Ivana, Prague
The verbal question about whether a ginseng can be grinded is the answer unambiguous - yes. Fresh root ginseng is not unlike most other Aralkovites woody and can be ground entirely like carrots. The same applies to any ginseng in a wet condition.
But you rather ask for powdered dried red ginseng. This already requires a practice. It is best to powder red ginseng, which is dry and hard. Such a ginseng can be manually powdered in a mortar with some effort. From the grinders I would recommend a coffee grinder with rotating knives if you know what I'm talking about.
There are other mills (shearing, spherical ...), but you do not have them at home. Anyway, whatever the grinder you use, you have to experiment with it a little. At higher temperatures, the ginseng red ginseng becomes sticky and there is a risk of clogging. Vegetable drug powder generally does not have a universal solution - every drug behaves differently. Herbal powders are easily leached and consumed, but they are easier to spoil, lose smell, oxidize and absorb air humidity. As with coffee, the herbs are better to powder just before use.
