Generally, the heat preservation capacity of a thermos cup drops by 2-8℃ per hour, so when pouring water at 100℃, it can exceed 60℃ after 6 hours, which is generally considered as a qualified thermos cup. If it can exceed 75℃, the heat preservation performance is excellent.

The time for soaking health tea in a thermos cup is generally about 1-2 hours. As long as it is a qualified thermos cup, the temperature can be kept above 80℃. For some thin slices of Chinese herbal medicines, effective components can be separated at this temperature.

However, it should be noted that hard Chinese herbal medicines such as shellfish, animal bones and mineral Chinese herbal medicines are not suitable for soaking in a thermos cup, because they need to be boiled at high temperature to separate out effective components, and aromatic Chinese herbal medicines such as mint, rose and Chinese rose are not suitable for soaking, otherwise the effective components will be denatured.

When choosing the health tea brewed in a thermos cup, the material must be marked with "food grade 304 stainless steel", so that the brewed tea has extremely low heavy metal content (within an acceptable safety range), good corrosion resistance and can be brewed for a long time.
