Geranium ointment is mainly used to treat eczema, carbuncles, boils, sores, boils and small areas of water and fire burns caused by accumulation of dampness and poison. This will work if the bubbling is caused by moist heat. While taking the medicine, stop eating spicy and irritating food, drink more water, and you can also drink honeysuckle water as tea. I wish you health and happiness. Hope this helps.
