Why does milk relieve spicy taste? Milk contains a lot of casein. Casein is a good emulsifier, which can effectively wrap the hydrophobic capsaicin and take it away, so it can relieve the spicy taste.
Spicy is not a taste, but a burning sensation produced by capsaicin stimulating nerves, which is actually pain.
Eating Chili, drinking vinegar or eating sweets can also achieve the effect of relieving spicy.
