What is the Moxibustion Sensation (Jiugan), and Why Does It Occur?

The sensation of moxibustion, also known as "Jiugan," occurs due to the dual action of the physical heat and the pharmacological effects of the moxibustion, which activate and promote the body's Qi. As the Qi circulates through the meridians, it interacts with the pathogenic factors in the body, leading to the expulsion of these harmful elements. This process triggers various moxibustion sensations such as heat, tingling, numbness, itching, or even no sensation at all. These reactions are signs that the moxibustion is having an effect on the body.

The appearance of these sensations indicates that the body's Qi is strengthening and is beginning to address the root cause of the issue, expelling the harmful energy from the body. It is a positive sign of improvement. In some cases, the sensation may even spread to other areas, suggesting that the moxibustion energy is following the meridians and continues to work on repairing the affected area.

However, not feeling any sensation does not mean that moxibustion is ineffective. Different people have varying reactions to moxibustion due to differences in moxibustion intensity, age, gender, individual constitution, and external factors such as environment and time. As long as moxibustion is applied correctly, the body will gradually become healthier over time.

什么是灸感，为什么会有灸感？

灸感是由于艾灸的热力与药理双重作用下，体内的经气被艾灸的温热激发和推动，经气在运行过程中与病灶的邪气相搏，和邪气外泻而引发的一系列灸感现象。这就是我们所说的灸感，也是艾灸起效的一个主要原因。根据不同的体质，灸感通常表现得也不一样：热烫、麻、刺、痒、没感觉等，出现这些感觉就表示艾灸正在对身体发挥调理作用。

灸感的出现甚至感传，意味着人体正气壮大，开始深入病灶，祛除病邪之气，是病情好转的象征。说明艾灸的纯阳之气沿着经络传导，处于修复病灶的持续过程中！在这个过程中可以加大量艾灸。

那么，若没有灸感，是不是说明艾灸不起作用？当然不是。每个人的情况不同，所产生的灸感反应也不同。艾灸的灸量、年龄、性别、个体体质、以及时间和环境的差异都会对灸感产生影响。只要坚持使用正确的艾灸方法，就会发现身体在潜移默化中变得越来越健康。
