Did you know your body has a built-in plumbing system?
Meet lymph - the hero working behind the scenes to keep your immune system healthy and functional.
Lymph is a clear, watery fluid that circulates throughout the lymphatic system and is key to your body's immunity. The lymphatic system is a complex network of vessels, tissues, and organs that work together to rid the body of toxins, waste, and other unwanted materials, while also playing a crucial role in fighting infections and diseases.
Main Functions of Lymph
Your lymph is essential for maintaining immunity and health. Three of its primary functions include:
- Transportation: Lymph serves as a transportation system, carrying white blood cells, proteins, and other substances throughout the body.
- Immune Response: Lymph is a main player in the body's immunity. It filters out harmful substances - such as bacteria, viruses, and cancer cells - and produces antibodies to fight off infections.
- Fluid Balance: Lymph helps maintain fluid balance within tissues by collecting excess fluid, proteins, and waste products from the spaces between cells and returning them to the bloodstream.
How Does the Lymphatic System Work?
Let’s take a deep dive to better understand how the lymphatic system works.
The lymphatic system functions as a part of the circulatory system, with a network of vessels that carry lymph throughout the body. The lymphatic system relies on the contraction of muscles and breathing movements to propel lymph fluid, which supports immune function and drainage [1].
Lymphatic vessels absorb excess fluid from the body's tissues and transport it through a series of lymph nodes, which act as filters. These nodes contain immune cells that help identify and destroy harmful substances, such as bacteria and viruses, before the lymph is returned to the bloodstream.
From the lymphatic vessels, lymph eventually drains into the thoracic duct or right lymphatic duct, which empty into large veins near the heart. This allows the lymph to re-enter the bloodstream, thus completing the cycle.
What about lymph nodes?
Lymph nodes are small, bean-shaped structures located throughout the body, primarily in the neck, armpits, groin, and abdomen. An adult has about 800 nodes which act as filtration stations. They trap and destroy foreign particles and cancer cells that may be present in the lymph fluid [2].
Have the sides of your neck ever felt swollen and painful when you get sick? When your body is fighting an infection, lymph nodes may swell and become tender, indicating increased activity in the immune system.
Lymphatic Health and Ayurveda
In Ayurveda, lymph is referred to as "rasa dhatu." According to Ayurvedic wisdom, rasa dhatu is considered the first product of digestion and is the foundational fluid for nourishing all the tissues of the body. Just as a healthy soil is essential for the growth of plants, rasa dhatu is considered the fertile ground from which all bodily tissues and organs get their nourishment and vitality.
Keeping lymph balanced and healthy is important as it impacts digestion, metabolism, immunity, and emotional stability.

How to Support Your Lymphatic System
Here are some ways to support your all-important lymphatic system:
- Stay Hydrated: Drinking plenty of water helps keep lymph fluid flowing smoothly and helps remove toxins and waste products from the body.
- Exercise Regularly: Physical activity, especially activities with rhythmic muscle movements such as walking, swimming, or yoga, can help stimulate lymphatic flow.
- Eat a Balanced Diet: A daily diet rich in fruits, vegetables, and lean proteins provides essential nutrients that support lymphatic function and overall immune health.
- Practice Dry Brushing: Dry brushing with a natural bristle brush to gently exfoliate the skin can help stimulate lymphatic flow. This detoxing practice helps remove dead skin cells and improve circulation, giving your skin a healthy glow and boosting your immunity. Check out our unique copper bristle dry brush!
