Self-limiting (a.k.a. self-recovering) is a term used in clinical medicine to refer to any disease whose natural history is to resolve without treatment. Many viral illnesses, e.g. upper respiratory tract infections, are self-limiting as patients will recover without taking any form of medicine.
任何干预，包括喝白开水，都可能加速或者延缓恢复。
自限这个词也不是指所有人都能够恢复，只是在统计学上针对大多数人成立。
