What are Sarcoids?
Sarcoids in horses are persistent, locally invasive skin tumours that commonly occur around the head, axilla (armpit), and groin regions. They are a type of skin tumour that does not typically spread to internal organs and are therefore classified as benign. (1) They behave like malignant tumours by invading surrounding tissues and frequently recurring after treatment. (2)
Why Sarcoids can be difficult to manage
Equine sarcoids occur in several distinct forms, and as a result, a treatment that is effective for one type may prove ineffective for another. Conventional treatment options include surgical excision, cryosurgery (freezing), laser surgery, and other veterinary interventions. However, because sarcoids are associated with a viral infection, affected tissues may continue to harbour the virus even after treatment, increasing the risk of recurrence. Consequently, many alternative treatments fail to address the underlying cause of the condition and may therefore provide only a temporary solution. (1)
Why Horse owners are using ArcEquine for Sarcoids
- Stimulating cellular repair and local tissue healing.
- Increasing blood flow and lymphatic drainage.
- Altering the sarcoid tissue in a way that may encourage regression or destruction of abnormal cells.
- Potentially influencing the local immune response against cells infected with bovine papillomavirus (a virus strongly associated with equine sarcoids). (3)

The most surprising thing that I noticed 3/4 weeks after the initial 6 week program with the Arc was that my mare’s sarcoid which she has had for over 10 years fell off! I had read that the Arc can help sarcoid so had been keeping an eye on it but never really thought anything would happen to it. The area where the sarcoid was has healed really nicely and you’d never know it had ever been there! (4)

I then stopped using it for a few months and noticed several sarcoids including one quite large one appeared on her belly, as before. Used the Arc every day for about a week then checked and they had all completely gone. That was around 3 months ago, using it now 2-3 times a week and no sign of any Sarcoids thankfully. (5)

Fabulous product! I have used the Arc to treat several large sarcoids on a new horse. The sarcoids have all dropped off, the wounds are healing well and the overall condition of the horse has improved. (6)
ArcEquine Protocol
Pre-2026 Programming:
3 weeks on Programme 1
2 weeks on Programme 2
3 weeks on Programme 3
After completing the above programme, revert to Programme 2 until the sarcoid drops off.
Post-2026 Programming:

2 weeks on Programme 3
3 weeks on Programme 4
After completing the above programme, revert to Programme 3 until the sarcoid drops off.
Important Considerations
- Not all sarcoids respond the same way.
- Correct diagnosis is essential.
- Some treatments can aggravate sarcoids if used inappropriately.
- Veterinary assessment should always come first.
- ArcEquine should not be presented as a guaranteed cure.
