Original M-T-G can make horses sensitive to sun. If your horse spends extended amounts of time in direct sunlight, consider applying in the early evening. This product may produce heat when applied, so take caution when applying under a leg wrap where the product may act as a sweat. 


Shake well before use. 

If using to treat skin conditions: apply a thin layer directly to the affected area. Don’t pick at scabs, as it can cause pain and swelling. M-T-G will help heal skin and soften scabs so they fall off naturally. No need to rinse after application. 

If using to prevent skin conditions, such as scratches, from coming back: apply a thin layer on desired areas before turnout in wet conditions. M-T-G will act as a barrier to help protect against re-infection.

If using to grow mane or tail: massage at the base of the mane or along the tailbone once per week.
