Heal them manually with items such as Recovery Potions. Stop making them work until they recover their health. Monsters at low health will show you their status with a scribble speech mark and refuse to work for you - there are three methods to deal with this:

Monsters who are put to work will require more fodder and will also gradually lose health. When working a field, monsters will water any tilled soil patches and crops, and they will harvest crops at the end of the day and put them in the Shipping Box. Every field is split into three sections and each monster can take care of one section. Once you have raised a monster's friendship level with you high enough, you can set them to work on your farm. There are two things that monsters can do for you on the farm: The higher your level is, the better your chance at taming success - try leveling up if you keep failing.

Your level matters when trying to tame monsters.

You can tame bosses upon rematch, but they require specific items.

You can use Medicinal Herbs or even Colored Grasses and still be successful.

While monsters all have some favorite items that you can use to increase your chance of success, you do not need to use them. This is useful when your item reserves are low. You can use the brush or a Love affinity weapon on a monster to increase the chances that a taming attempt will be successful. They will be added to your party automatically, though you can talk to them to send them back to your farm. If it becomes a huge heart, on the other hand, you have successfully tamed the monster, and you will have to name it.

If the heart becomes a skull, you have failed and must try again. It will gradually grow larger until it becomes a skull or a gigantic heart. When in the field, throw an item at them - they will get a speech bubble above their head with a heart inside it. Taming monsters is a relatively simple ordeal.
