Thick and white tongue coating may be caused by insufficient hygiene, food retention, and damp-cold in the spleen and stomach. Treatment should be tailored to the cause. 1, Insufficient hygiene: Not paying enough attention to the oral hygiene, not rinsing the mouth promptly after eating, may lead to food residue on the tongue surface. It is necessary to maintain good brushing habits to avoid food residue.

2, Food retention: Regular consumption of greasy and spicy foods may lead to dysfunction of the spleen and stomach, and excessive intake of food may also trigger conditions such as thick and white tongue coating. It is necessary to maintain a diet mainly of light and easily digestible foods, and to eat less and more frequently.

3, Spleen and stomach damp-cold: Long-term exposure to cold and damp environments, and excessive consumption of cold and cool foods, may lead to the accumulation of coldness in the spleen and stomach, causing thick and white tongue coating. It is necessary to follow the doctor’s advice and take medications such as Fuzi Liren Wan, Danshen Liren Wan, Huoxiang Zhengqi Wan, etc.
