Fleshy thorns on the tongue are mostly caused by the rise of stomach fire and liver fire. Long-term consumption of spicy, oily and indigestible food can cause stomach fire to rise. High work stress, long-term mental tension and anxiety, quarrels, and sulking can cause liver fire, all of which can cause inflammation of the mucous membrane papillae of the tongue, making the tongue look like a barb. Vitamin and trace element deficiencies in the body can also trigger tongue inflammation, and ulcers in the mucous membrane of the tongue, leading to local redness, swelling and ulceration, can also make the tongue grow fleshy spurs. Herpes virus or Candida albicans fungal infectious stomatitis causing blistering on the surface of the tongue, erosion or the appearance of white spots and white hyperplastic pseudomembranes can also cause the tongue to grow fleshy spurs. Those suffering from lichen planus of the tongue mucosa, lichen planus has various manifestations on the tongue, causing white hyperplastic plaques, erosion and bleeding lesions on the tongue.
