Commonly used medications include Yupingfeng Granules, Huangqi Granules, Zhenqi Fuzheng Granules, Pidotimod Oral Liquid, Transfer Factor Oral Solution, and others. Detailed analysis is as follows:

1. Yupingfeng Granules

Composed of Huangqi (Astragalus), Baizhu (Atractylodes macrocephala), and Fangfeng (Saposhnikovia divaricata), Yupingfeng Granules have the functions of invigorating qi, consolidating the body's defensive barrier, and stopping perspiration. They can enhance the body's defensive functions and reduce the frequency of colds caused by qi deficiency and an unstable defensive barrier, making them suitable for individuals aiming to enhance immunity to prevent colds.

2. Huangqi Granules

Huangqi Granules mainly contain Huangqi (Astragalus), which functions to replenish qi and consolidate the body's exterior. They can improve symptoms such as fatigue due to qi deficiency and spontaneous perspiration caused by a weak exterior. By enhancing the body's resistance, they help reduce the occurrence of colds and assist in regulating immunity and can be taken under a doctor's guidance.

3. Zhenqi Fuzheng Granules

Zhenqi Fuzheng Granules are made from Huangqi (Astragalus) and Nuzhenzi (Ligustrum lucidum), and they help enhance human immune function. They are suitable for weakness caused by various diseases, can strengthen the body's resistance, reduce the likelihood of catching a cold, and are particularly appropriate for individuals with weak immunity.

4. Pidotimod Oral Liquid

Pidotimod Oral Liquid primarily contains pidotimod, which can stimulate the body's immune system and enhance non-specific immune responses. It helps reduce the frequency of respiratory infections and plays a regulatory role in boosting immunity to prevent colds.

5. Transfer Factor Oral Solution

Transfer Factor Oral Solution consists of peptides, amino acids, and nucleotides extracted from the spleen of healthy pigs. It can enhance or regulate both humoral and cellular immune functions. It can assist in improving the body's resistance and reducing the occurrence of colds, making it one of the commonly used medications.

In addition, individuals who need to enhance immunity to prevent colds may also use other suitable medications under a doctor's guidance. During medication, attention should be paid to maintaining regular作息 (作息 should be translated as "rest and work patterns" or "daily routines"), engaging in appropriate physical activity, following a balanced diet, and consuming more foods rich in vitamins to help improve the body's resistance.
