Phlegm is a required and a normal sticky secretion of the mucus membranes that performs various lubricating functions within the body. However, sometimes there is excessive production of phlegm which may be on account of external factors such as climatic conditions, infections, genetics and undigested food stagnating in the stomach. Too much phlegm production tends to be annoying and may result in the individual suffering from an annoying cough or a stuffy nose. As a result the individual’s day to day activities are hampered and they may be left feeling weak from the constant coughing and sneezing. Herbs for phlegm are broadly classified into two categories. The first are those that are used for resolving the problem of cold phlegm which tends to be thin, moist and clear; the second refers to herbs that are used to resolve hot phlegm which tends to be thick, drier and even discolored at times. Many a times, herbs from both categories are mixed together to act as an effective cure from phlegm. One of the common herbs for phlegm is the bamboo which typically means the shavings of the bamboo stem. This herb has a mild cold nature and a sweet taste. When consumed this herb for phlegm tends to resolve the problem of thick phlegm and also controls vomiting. The active components in the bamboo are the triterpenes which reduce inflammation of the stomach and also thicken phlegm. Similarly another herb for phlegm is bamboo sap either dried or fresh which are more cooling in nature as compared to bamboo shavings. One of the highly effective herbs for phlegm is clam shells which are obtained from the species of bivalves. Clam shells helps in resolving the problem of phlegm masses which are present in the sputum that may be there in the lungs. This herb has a salty taste and tends to have a positive influence on the lungs and the liver. The active component in clam shells are protein and calcium salts. Bulbifera is also one of the commonly used herbs for phlegm which helps in reducing swellings such as lung abscess and even hyper-thyroidism.
Bulbifera is usually bitter to taste, non poisonous, mild in nature and tends to reduce heat by cooling the blood. It is also effective in removing toxins from the goiter thereby curing it. Another herb for phlegm is the Fritillaria which is used to treat phlegm that is produced in excess and is sticky. The active components of the Fritillaria are steroidal alkaloids which are known to have anti-inflammatory, sedative and phlegm resolving properties.
