Flower of Sulphur, also known as sublimated sulfur, is a natural supplement that possesses antibacterial, antifungal, and anti-inflammatory properties.

It has long been used in horse care to improve hoof health, treat skin problems, and combat parasites.

But how long should you give your horse Flower of Sulphur and what should you consider before incorporating it into your horse's diet?

In this detailed guide, we will explore the uses of Flower of Sulphur, its potential benefits and risks, as well as the recommended duration of feeding.

How long should you feed Flower of Sulfur to horses?

How long you should feed Flower of Sulphur depends on why you are using it.

1. Short-term use (1-2 weeks)

For temporary issues your horse may have, such as itchy skin due to seasonal allergies or as a pest control agent, short-term supplementation for 7 to 14 days is recommended.

A typical dosage is between 1 teaspoon and 1 tablespoon (approx. 5-15 grams) daily, mixed into feed, although this varies widely depending on the size of the horse and the source of the recommendation. (Adult horses (1,000-1,200 lbs): 15-20 grams daily.)

2. Seasonal Use (Spring and Autumn)

Try it during bug-prone seasons, such as spring or autumn, giving 10-20 grams daily for a few weeks, then stop when the problem resolves.

3. Long-term use (not recommended)

You should not feed Flower of Sulphur to your horses for an extended period, as it can be toxic.

Too much inorganic sulfur over a long period can upset your horse's stomach, cause colic, or in rare cases, even lead to sulfur poisoning.

Recommended Dosage for Your Horse

There is no standard dose for Flower of Sulphur, but here are some recommendations:

• Horses (1,000-1,200 lbs): 15-20 grams per day.
• Ponies: 10-15 grams per day.

These are reasonable dosages based on historical practices and not on studies, so you should be cautious.

Start with a small amount, e.g., 5 grams, to see how your horse reacts, and do not exceed 20 grams without consulting a veterinarian.

Potential Side Effects and Precautions

While Flower of Sulphur is generally safe, excessive use can lead to the following side effects in your horse:

• Digestive upset – Excessive use can cause colic or diarrhea.
• Sulfur Toxicity – Rare, but possible with excessive long-term intake.
• Allergic reactions – Watch for skin irritation or breathing difficulties.

Key Takeaways

You can feed Flower of Sulphur to your horse for 1-2 weeks to treat specific problems, such as skin irritation or pests, by administering a small, monitored dose.

However, for longer-term use, regular breaks may be necessary.

For your horse's best health, offer excellent feed and consult your veterinarian about proven and effective supplements.
