1. Insulation: The insulation function of the thermos bottle may not be suitable for steeping wolfberry and red dates because it is designed to keep hot liquids warm or cold liquids cold.
2. Material: The material used to make the insulation layer of the thermos bottle may not be suitable for steeping wolfberry and red dates. Some materials may alter the natural taste and aroma of the ingredients, which can affect the overall flavor of the drink.
3. Hygiene: Many people use their thermos bottles for a long time without proper cleaning, which can lead to the accumulation of bacteria and affect the health of the user. Steeping wolfberry and red dates in an uncleaned thermos could result in the formation of mold, fungus, or other harmful microorganisms.
4. Pressure: Steeping wolfberry and red dates in a thermos bottle that is not designed for this purpose can create pressure inside the bottle, causing it to leak or burst. The high temperature of the water can also damage the seals or other parts of the thermos.
5. Aesthetics: Finally, using a thermos bottle for steeping wolfberry and red dates may not be aesthetically pleasing, as the bottle's design and color may not complement the traditional look of the ingredients. Additionally, some people prefer to use traditional containers, such as clay pots or glass jars, to steep their herbal teas.
