Infused, handpicked selection of medicinal healing herbs that help relieve menstrual pain and discomfort. By infusing cannabis flowers with organic carrier oils (olive oil, apricot kernel oil, avocado oil, and jojoba oil), all of which contain medicinal properties themselves, a wholesome, concentrated, organic salve. This all natural salve will help reduce menstrual pain and discomfort no matter the place or time, whenever relief is needed.

Cosmic Opinion
We have found this rub works great on any bodily pain. We use it for sore muscles after a workout. Perfect for arthritis pain. Takes about 30 minutes to totally feel the effect. So impressive, It really works! We have been working on one large jar for months so it's very economical. Lovely herbal aroma: don't worry you won't smell like marijuana.
