Introduction

The optimal timing for taking traditional Chinese medicine (TCM) depends on the type of herbs being used. For tonic herbs such as ginseng and astragalus, it is generally recommended to take them on an empty stomach, preferably in the morning or at noon, to enhance absorption. For non-tonic herbs, it is advisable to take them 30 minutes to one hour after a meal to reduce gastrointestinal irritation and improve absorption. However, regardless of the type, it is important to follow the instructions provided by a healthcare professional.

Generally speaking, there is no definitive statement regarding the best time to take traditional Chinese medicine (TCM) for optimal effectiveness. The timing mainly depends on the type of TCM being used. If it is a tonic herbal medicine, it is better to take it on an empty stomach before meals. If it is non-tonic herbal medicine, it is better to take it about half an hour after a meal. Detailed explanations are as follows:

If the chosen TCM belongs to the tonic category, such as ginseng, astragalus, or angelica sinensis, it is recommended to take it before meals on an empty stomach, preferably 30 minutes to one hour before breakfast or lunch. This is because taking tonic herbal medicine on an empty stomach allows the medicinal liquid to directly contact the mucous membrane of the digestive tract, thereby enhancing drug absorption and achieving better therapeutic effects for body regulation. Additionally, the efficacy of such medicines won't be affected by food dilution in the stomach.

However, if the chosen TCM is non-tonic, it is recommended to take it after meals, preferably half an hour to one hour post-meal. Non-tonic herbal medicines may irritate the intestinal mucosa, and taking them after meals can reduce the irritation to the gastrointestinal mucosa, alleviating symptoms such as nausea and vomiting. Moreover, taking non-tonic herbal medicines together with food helps delay the gastric emptying time, thus promoting drug absorption.

It should be noted that regardless of which type of TCM is taken, it should always be taken according to the doctor's instructions, avoiding self-medication or combining it with other herbal medicines without guidance. Additionally, attention should be paid to the dosage, avoiding擅自 (self-adjusting) increases in medication dosage.

Can traditional Chinese medicine be used for treating white lung in interstitial pneumonia?

In general, whether patients with interstitial pneumonia and white lung can take traditional Chinese medicine (TCM) needs to be determined based on individual circumstances. During the stable phase of the disease, TCM may be used under a doctor's guidance to assist in调理 (regulating and improving body functions). However, during an acute exacerbation, taking TCM might not be appropriate. To prevent worsening of the white lung condition associated with interstitial pneumonia, it is recommended to properly care for the lungs in daily life.
