Northern almonds moisten the lungs and relieve asthma, showing significant efficacy for symptoms like excessive phlegm, coughing, and wheezing caused by colds.
Since apricot kernels primarily enter the lung meridian with dispersing and opening properties, they can be combined with various Chinese herbs to address different lung-related cough and asthma conditions. For wind-cold cough and wheezing, they are paired with ephedra and licorice to disperse wind-cold, promote lung function, and relieve wheezing—as in the San'ao Decoction. For wind-heat cough, they are combined with mulberry leaf and chrysanthemum to disperse wind-heat, promote lung function, and stop coughing—as in the Sangju Decoction.For dry-heat cough, it is combined with Mulberry Leaf, Fritillary Bulb, and Glehnia Root to clear lung heat, moisten dryness, and stop coughing, as seen in the Mulberry and Apricot Decoction.Traditional Chinese medicine considers water chestnuts cold in nature and sweet in taste, entering the lung and stomach meridians.

They are commonly used for fluid depletion due to heat diseases, restlessness and thirst, nausea and vomiting, dry lung cough, and dry, hard stools.
Water chestnuts are delicious, but hygiene is crucial when consuming them. Growing in muddy marshes, their surfaces harbor significant bacteria and parasite eggs—particularly Clonorchis sinensis eggs. Those who prefer eating them raw must thoroughly wash water chestnuts under running tap water, peel them, and blanch in boiling water before consumption.
