Fish petroleum ointment should not be used after the abscess has broken down, but can be applied externally after removing the pus until the boil is healed.
It has anti-inflammatory, antiseptic and decongestive effects, and is slightly irritating. It is often used in the red and swollen stage of boils, but cannot be used on broken skin. Therefore, it should not be used after the abscess has broken down, but should be used after the abscess has been broken down, to remove the pus, and then apply herbal ointment to remove the decay and regenerate the muscle (antidote and regenerate the muscle ointment, comfrey ointment, etc.) until the boil is healed.
It should be noted that boils should not be squeezed after rupture to avoid spreading of infection and aggravation of the condition. It is recommended that patients should not treat the boils on their own, but should ask professional doctors to regulate the treatment in order to heal the boils as soon as possible.
