The practice of 'dánh cảm', involving the use of boiled chicken egg yolks, coins, or silver chains to rub the body, is a long-standing folk remedy. It falls under a category of traditional therapies known as 'biem phap', which also includes practices like 'cao gio' (coin rubbing), 'chich le' (pricking), and 'giac hoi' (cupping).

According to traditional medicine, 'dánh cảm' aims to clear meridians and collaterals, improve the circulation of qi and blood, relax muscles, and regulate meridian energy flow. This practice is believed to boost the body's vital energy, expel 'evil qi' (pathogenic factors), and dissipate superficial heat.

This method is suitable for fevers caused by external pathogenic factors, but not for all types of fever, such as those arising from yin deficiency. 'Dánh cảm' may help alleviate mild fevers, muscle aches, stiff necks, and headaches associated with wind-cold, heat-cold, or cold-cold syndromes, or fevers resulting from sunstroke that cause stagnation of yang qi.

'Dánh cảm' can improve microcirculation and dilate capillaries through local stimulation. However, it does not directly eliminate infectious pathogens nor significantly influence the body's temperature regulation. Therefore, this method is not recommended for high fevers.

For adults with a weak constitution, a tendency to bleed, compromised skin (such as ulcers or existing purpuric rashes), or cardiovascular conditions, 'dánh cảm' may provoke adverse reactions. Consequently, individuals in these categories should avoid this practice.

Children possess delicate skin and immature internal organs, and their illnesses can progress rapidly. Therefore, this method is not advisable for reducing fever or relieving colds in children. 'Dánh cảm' in children risks causing skin damage, increasing infection risk, or even elevating fever. Such outcomes could delay crucial treatment for high fevers caused by infections or conditions like autoimmune diseases, cancer, or hematological disorders.
