Final answer:
An essential oil that promotes lymph drainage aids in reducing edema and lowering blood pressure by improving lymphatic system function, which includes the draining of chyle into blood circulation and the liver's processing of nutrients.
Step-by-step explanation:
An essential oil used for its lymph drainage benefits is particularly helpful for the lymphatic system, which includes main lymphatic ducts in the chest from which it drains into the blood circulation. This process is crucial as it helps to reduce swelling, also known as edema, which is caused by an excess buildup of fluid in the body. It is also used to help lower blood pressure.
When the lymphatic system functions efficiently, it contributes to the removal of excess fluid from tissues, assists in immune response, and facilitates the absorption and transport of fatty nutrients in chyle to the liver. The liver plays a significant role in processing these nutrients along with other substances that reach it directly through the bloodstream.
