What Is Frankincense Oil?
Frankincense oil is extracted from the gum or resin of frankincense or olibanum trees, of the genus Boswellia carteri. Common species used to extract essential oil include Boswellia carterii, B. frereana, and B. sacra. The main components of this essential oil (depending on the species and chemotype) are alpha-pinene, octanol, alpha-thujene, octyl acetate, incensole, and incensole acetate. Frankincense has been a popular ingredient in cosmetics and incense burners for centuries. It has even been found in the remains of ancient Egyptian and Anglo-Saxon civilizations. Furthermore, it is closely associated with religious traditions and rites, particularly the Christian tradition.

Improves Oral Health
Frankincense oil is best known for fighting harmful microorganisms. These properties work well for maintaining dental health as well. While it finds wide dental uses in several cultures where it is hailed for its protective properties, a double-blind randomized clinical trial has found it to be especially useful against gingivitis. The study deems this to be a safe and cheaper medicine that can be used in aid of conventional treatment. 
Frankincense oil is experiencing growing popularity in the world of clean, alternative beauty. While its antimicrobial properties prove useful on the path to clear skin, frankincense oil also works well as an astringent. Moreover, it works at deeper levels for troubled skin thus providing more sustainable results and works especially well for oily skin types. You can make your serum or oil blend at home or can opt for several readily available products in the market. 
It can help eliminate sun spots, remove micro-wrinkles around the eyes and cheeks, and generally tone and tighten skin all over your body, while simultaneously raiding cell regeneration. 
Frankincense essential oil reduces obstructed and delayed menstruation and delays the advent of menopause. It also helps with other symptoms associated with menstruation and premenstrual syndromes (PMS), such as pain in the abdominal region, nausea, headache, fatigue, and mood swings.
This is one of the most interesting properties of frankincense oil. When applied topically or inhaled, it can help the scars and marks of boils, acne, and pox on the skin fade at a much faster rate. This also includes the fading of stretch marks and surgery scars, making it quite useful for pregnant women and new mothers. 
Fed up with those antacids? You should try frankincense oil instead. This oil has digestive properties without any side effects, and it facilitates digestion the way most medicines should, unlike common antacids which only suppress the symptoms. This oil speeds up the secretion of digestive juices (gastric juices, bile, and acids) in the stomach and facilitates the movement of food through the intestines by stimulating peristaltic motion. This means an all-around improvement in the digestion of food.  
Reduces Respiratory Issues
It soothes the cough and eliminates phlegm deposited in the respiratory tracts and the lungs. Frankincense essential oil also provides relief from bronchitis and congestion of the nasal tract, larynx, pharynx, bronchi, and lungs. Its antidepressant and anti-inflammatory properties also help relax the breathing passages, which can reduce the dangers of asthma attacks, and its antiseptic qualities give it the reputation of being an immune system booster! It also eases body pain, headaches, toothaches, and balances the rise in body temperature commonly associated with colds.    
Frankincense forms an important part of several rituals in some cultures. It is meant to purify and repel negativity. Interestingly, similar effects are to be observed in frankincense oil. The results of a 2019 animal study found that the oil can easily help lower stress in rats by reducing sleep debt as well as maintaining antioxidant capacity. It was used topically in sleep-deprived rats with jojoba oil as a carrier. 
Keeps Uterus Healthy
Frankincense oil is also very good for uterine health. Since it regulates the production of the estrogen hormone, it reduces the chances of post-menopause tumor or cyst formation in the uterus. It also keeps the uterus healthy by regulating proper menstrual cycles. It regulates gynecologic conditions or stressors that can lead to complicated dysfunctions in certain women. 
Speeds up Healing
