Understanding Thermic Properties in Traditional Medicine

The concepts of "heaty" and "cooling" foods are not based on their literal temperature but on their effect on the body's energy, or 'Qi', according to Traditional Chinese Medicine (TCM). Similarly, Ayurveda categorizes foods by their warming or cooling virya, or energy. These principles guide dietary choices to maintain internal balance, especially in different seasons or for various body constitutions.

Buckwheat Tea in Traditional Chinese Medicine (TCM)

According to TCM, buckwheat (often consumed as soba-cha) is decidedly cool in nature. It is valued for its ability to clear heat, resolve dampness, and circulate Qi.

Flavor: Sweet.
Channels: It primarily affects the Large Intestine, Spleen, and Small Intestine channels.
Actions: Its key actions include clearing heat, resolving dampness, strengthening the intestines, and improving appetite. This makes it a popular beverage in China, Korea, and Japan, especially during warmer months to counteract summer heat.

Buckwheat's Role in Ayurveda

Ayurveda offers a contrasting perspective on buckwheat's thermal qualities. In this ancient Indian healing system, buckwheat is considered warming. It is characterized by sweet, pungent, and astringent tastes with a heating virya (energy).

Balancing Doshas: It is most balancing for Vata and Kapha doshas, particularly during cooler seasons, due to its warming and drying effects.
Moderation for Pitta: Because of its heating quality, individuals with a Pitta constitution are advised to consume it in moderation to avoid increasing internal heat.
Mineral Absorption: Ayurvedic practitioners also note that soaking buckwheat can reduce phytic acid, improving the absorption of its minerals like magnesium, copper, and zinc.

How to Enjoy Buckwheat Tea

This caffeine-free beverage can be enjoyed hot or cold, offering versatility for different preferences and times of the year.

For a refreshing, cooling drink: Brew it hot, then let it cool before refrigerating. Serve over ice with a slice of lemon for an extra refreshing twist. This is a common practice in East Asian countries during the summer.
For a warming beverage: Enjoy it fresh and hot, especially during colder seasons. Its nutty aroma and flavor make it a comforting alternative to coffee or traditional tea.

The Health Benefits Beyond Temperature

Regardless of the tradition, buckwheat tea is celebrated for its health-promoting properties.

Cardiovascular Health: Rich in rutin, an antioxidant that strengthens capillaries, improves blood circulation, and helps lower blood pressure.
Digestive Aid: Its fiber content helps regulate bowel movements and support gut health. It is also known to soothe the stomach and assist with digestion.
Blood Sugar Management: It contains D-chiro-inositol, which helps regulate blood sugar levels, making it beneficial for those with diabetes.

Navigating the Contradiction

The discrepancy between TCM and Ayurvedic views on buckwheat's thermal nature is a fascinating example of different traditional frameworks. These systems assess foods based on different sets of principles and observations. For the average consumer, this means that the perceived effect may depend on individual body constitution and climate. An individual with a "heaty" body type in TCM may find relief from summer heat with cool buckwheat tea, while someone with a Kapha (heavy, damp) imbalance in Ayurveda might benefit from buckwheat's warming, drying qualities in winter.
