The concept of Heat and Cold is very important in Chinese Medicine theory. Think about it more like an inner balance of temperature as opposed to a thermometer reading. Eg: Peppermint tea is 'hot' to touch, but has a 'cool' property. Heat: Having excessive Heat can lead to symptoms like feeling warm, inflammation, red eyes, thirst and dry mouth. Picture it as the body's inner thermostat running too high. Cold: a lack of internal warmth, leading to excessive Cold in the body and its systems. This can lead to discomfort, poor circulation, and lingering “cold sensations” in the body. Note: Hot, Heat, Heatiness; and Cold and Cool can be used interchangeably.
