Dear 米豆,
Thank you for your inquiry regarding tongue coating and its connection to digestive health. The color and texture of the tongue can indeed provide valuable insights into a person's digestive health and overall well-being. In traditional Chinese medicine, for instance, the tongue is often viewed as a reflection of the internal organs, particularly the digestive system. Changes in tongue coating can indicate various health issues, including imbalances in the digestive tract.

When you notice that your tongue turns yellow after consuming certain foods or beverages, such as milk tea or black tea, it may be due to the pigments in these items. However, a persistent yellow coating can also suggest issues related to heat in the body, which may be linked to digestive problems or an imbalance in your diet. It's essential to consider other symptoms you may be experiencing alongside the tongue coating, such as discomfort or pain in the stomach.

Regarding your experience with taking capsules like reishi mushroom (靈芝) or calcium supplements, and subsequently feeling discomfort or a burning sensation in your stomach, this could indicate a few possibilities. First, some supplements can be harsh on the stomach lining, especially if taken on an empty stomach. Calcium supplements, in particular, can cause gastrointestinal discomfort in some individuals, leading to symptoms like bloating, gas, or even pain. If you are taking these supplements without food, it might be beneficial to try taking them with meals to see if that alleviates your symptoms.

Additionally, if you are experiencing consistent discomfort after taking these supplements, it may be worth considering whether you have an underlying condition, such as gastritis or acid reflux. These conditions can be exacerbated by certain foods, beverages, or supplements, leading to symptoms like pain or a burning sensation in the stomach. It is advisable to consult with a healthcare professional who can evaluate your symptoms more thoroughly and possibly recommend tests to rule out any significant gastrointestinal issues.

In summary, while the color of your tongue can provide insights into your digestive health, it is essential to consider the broader context of your symptoms and dietary habits. If you continue to experience discomfort, it would be prudent to seek medical advice to ensure that there are no underlying health concerns that need to be addressed. Maintaining a balanced diet, staying hydrated, and being mindful of how your body reacts to specific foods and supplements can also contribute to better digestive health.

Wishing you good health and well-being!
Best regards.
