中医拔火罐的原理-神秘的起源（终）

What Is Cupping/Scraping?
什么是拔罐和刮痧？
Cupping is one of the oldest “external” methods of TCM. Cupping is a type of Chinese massage, consisting of placing several glass or plastic “cups,” or open spheres, on the body.
「拔火罐是中医最古老的“外治法”之一。拔火罐是一种中医按摩，由在身体上放置几个玻璃或塑料“罐”或开口的球形容器组成。」
The cups are warmed using a cotton ball or other flammable substance, which is placed inside the cup to remove all the oxygen. The substance is then removed before the practitioner places the cup against the skin.
「这些杯子是用棉球或其他可燃物质放置在罐里以除去里面所有的氧气。」

The air in the cup then cools, creating lower pressure inside the cup, thus creating a vacuum and allowing the cup to stick to the skin. Fleshy sites on the body, such as the back and stomach, are the preferred sites for treatment.
「然后，在医生将罐放在患者皮肤上之前，会首先将这种物质移走。然后罐里的空气冷却后，随之压力也降低了，这样就形成了真空，罐就能贴在皮肤上了。人体上肌肉丰厚的部位，如背部和胃脘部，是治疗的首选部位。」
Depending on the condition being treated, the cups will be left in place from 5 to 10 minutes. When combined with massage oil, the cups can be slid around the back while drawing up the skin.
「根据具体的治疗情况，留罐时长5到10分钟不等。当配合使用按摩油，可以在背部进行滑罐治疗。」
Drawing up the skin is believed to stimulate the flow of blood, balance and realign the flow of Qi, break up obstructions, and create an avenue for toxins to be drawn out of the body.
「一般认为，拔火罐可以促进血液的流动，平衡和调整气的运行，疏通经脉，创造能够使毒素排出身体的出路。」
Scraping, or “Gua Sha,” is a folk medicine technique that uses pieces of smooth jade, bone, animal tusks, horns, or smooth stones to scrape along the skin to release obstruction and toxins that are trapped at the surface of the skin. The scraping is done until red spots then bruising cover the treatment area.
「刮痧，是一种民间医学技术，使用光滑的玉石、骨头、动物的象牙、角或光滑的石头沿着皮肤刮拭，以疏通停留在皮肤表面的阻滞和毒素。一直刮到红点和瘀斑出现在整个治疗区域为止。」
It is believed that this treatment works for almost any ailment. The red spots and bruising take 3 to 10 days to heal, and may be misconstrued by others as a sign of abuse if they are not informed about the treatment.
