On howrse all food and health objects last forever. If it is something else from the Black Market I don't know exactly how long.
For the game 'horwse' it is free, but you have to pay to get passes
When you have been on Howrse long enough you can buy a Horse from the auctions or Private Sales
Objects which are high quality last longer than ordinary objects. High quality objects usually have more cost. Objects with less quality may become unusable in a small period.
You will have to pay
It appears there may have been a typo in your question. "Horwse" does not have a known meaning. If you have a specific question or meant to ask something else, please clarify and I'd be happy to help.
The answer differs from one disease to the next.
