Lymphatic system in horses - How to support it

Lymphatic system in horses – How you can support it naturally

The horse's lymphatic system is a key element for health, well-being, and performance. It's often only noticed when swelling, swollen legs, or slowed recovery have already occurred. But what exactly is the lymphatic system, what functions does it perform—and how can you specifically support it?

In this article, you will learn how your horse's lymphatic system works and what measures you can take to support it gently and naturally .

What does the lymphatic system do in horses?

The lymphatic system is part of the immune system and runs throughout the horse's body. It has important functions:

• Removal of metabolic waste and excess tissue fluid
• Strengthening the immune system
• Filtering of pathogens, toxins and foreign substances
• Support in regeneration after injuries or stress

Unlike the circulatory system, the lymphatic system doesn't have a central pump like the heart. It relies on movement and well-functioning muscles to transport lymph fluid throughout the body.

Symptoms of a strained lymphatic system in horses

A congested or overtaxed lymphatic system often manifests itself through various symptoms, for example:

• Swollen legs , especially after prolonged standing
• Swelling of the abdomen, chest or other parts of the body
• Inertia and slow regeneration
• Increased susceptibility to infection
• Congestion after injuries or operations

If you observe such symptoms, it may be helpful to specifically support your horse's lymphatic system. However, please note: In case of acute or unclear symptoms, you should always consult your veterinarian first.

How can you support your horse's lymphatic system?

1. Movement is key

Since lymph is only transported through muscle movement, regular exercise is essential for the lymphatic system. This includes:

• Daily grazing or free movement on the paddock
• Light ground work or guided walks
• Lunging without side reins to promote natural movement

The more regularly your horse exercises, the better the lymph flow can function and the body can eliminate toxins.

2. Lymphatic drainage and massage

Targeted manual lymphatic drainage can help get the lymph flowing—especially in horses that tend to have swollen legs or have been standing for extended periods. Gentle massages or special brushing techniques (e.g., with lymphatic brushes) also stimulate blood circulation and lymph flow.

Tip: Have an experienced therapist or equine physiotherapist show you how to perform simple massage techniques yourself.

3. Nutrition and herbs for lymphatic support

A healthy, balanced diet is the foundation for a functioning lymphatic system. There are also natural herbs that can gently stimulate lymph flow—ideal for support during exercise or recovery.

Proven herbs for lymphatic support in horses:

• Nettle – stimulates excretion via the kidneys and lymph
• Goldenrod – supports kidneys and metabolism
• Birch leaves – promote fluid exchange in the tissue

These herbs can be administered, for example, as a dried mixture or in the form of special supplementary feed.

Note : Herbs and herbal supplements can support the body's natural functions, but are not a substitute for medical treatment.

4. Keep an eye on your water balance

For proper lymph flow, your horse needs sufficient fluids. Ensure fresh, clean water is always available—both in the stable and in the pasture. In summer, you can also encourage water intake with moist mash or succulent feed such as carrots or beets.

When should a veterinarian be consulted?

Persistently impaired lymph flow can indicate serious illnesses—such as infections, cardiovascular problems, or metabolic disorders. If your horse regularly suffers from swollen legs, exhibits unusual swelling, or deteriorates in general condition, a visit to the veterinarian is essential.

How to naturally strengthen your horse's lymphatic system

A healthy lymphatic system is the foundation for a strong immune system and your horse's overall well-being. With regular exercise, gentle care, targeted nutrition, and supportive herbs, you can do a lot to keep the lymph flow active and your horse feeling well.

Observe your horse carefully, ensure variety in exercise and feeding, and resort to natural support when necessary – this will keep the lymphatic system in balance.
