Study Notes

Cupping Therapy

Cupping therapy likely originated in China around 1500 BCE and is still practiced today.
The process involves heating air in bulb-like cups to create reduced pressure before placing them on the skin.
Fire cupping, a traditional method, uses a lit stick or alcohol-soaked cotton to heat the air and remove it from the cup.
Cups can range from 60 mL to 125 mL; smaller cups are for bony areas and larger for fleshy parts.
Claims suggest cupping boosts blood flow, but evidence supporting this is limited; some argue it can lead to broken blood vessels, impeding circulation.

Scientific Principles of Cupping

Heating air in the cup increases the velocity of particles, leading them to expand and some to escape.
Gas pressure is determined by particle collisions against container walls; heated particles maintain pressure despite fewer numbers.
When the flame is removed, the air cools, slowing particle movement, reducing pressure, and creating a suction effect on the skin.

Modern Cupping Techniques

Contemporary methods may use vacuum pumps to create low pressure without the risk of burns.
These pumps effectively draw air from the cup, causing the skin to bulge into the cup.

Experiment: Hard-Boiled Egg and Vacuum

Demonstrates principles similar to cupping: a lit strip of paper inside a bottle reduces pressure as the flame consumes oxygen, creating a vacuum that pulls the egg into the bottle.
Students can create particle diagrams to visualize air changes inside and outside the bottle during the experiment.
