幫我翻釋一下

煲水 = boil water
如果生病時,可吃藥. = If you are sick, you could take medicine.
受傷時,可在傷口上塗藥水. = When injured, you could apply medicine to the wound.

It sounds funny in English without “you”so I added it in, hope you don’t mind.
Hope this helps!! X ]

煲水 - heat the water
如果生病時,可吃藥 - you can take some medicine if you are not feeling well
受傷時,可在傷口上塗藥水 - you can put on some medicine if you got injured.
