Rose essential oil is a unilateral essential oil for nourishing uterus, which can improve or even treat dysmenorrhea and other symptoms. But the usage you said is really unheard of. Moreover, the concentration of rose essential oil is extremely high, so it is not recommended. The essential oil used in underwear is tea tree essential oil.

However, if you have inflammation or want to prevent inflammation, it is recommended to use tea tree essential oil, because tea tree essential oil is a unilateral essential oil with first-class bactericidal and anti-inflammatory effects, which can treat some gynecological inflammation and prevent it. Drop two drops of tea tree essential oil on underwear at a time. Do not dilute it. But you can't use it every day, because tea tree essential oil is negative, so you must use it for two days, and then stop using it for one or two days, otherwise it may lead to problems such as dryness and frigidity.
