What Are The Benefits Of Sandalwood Essential Oil?
1. May Improve Complexion
Alpha-santalol, another major constituent of sandalwood oil, inhibits tyrosinase and cholinesterase (enzymes that catalyze the production of melanin pigments). Due to this activity, the oil is an active ingredient in several skincare products (4).
Sandalwood essential oil is also enriched with sesquiterpenoids (molecules that deliver oxygen molecules to cells), which act as coolants and relaxants (4).
Some believe sandalwood oil may also help remove dark spots, although there is no research to support this.
2. May Treat Acne
Sandalwood essential oil has anti-inflammatory, antimicrobial, and anti-proliferative properties. Hence, it can be a promising treatment for acne and other skin problems like eczema, psoriasis, warts, etc. (1).
Adolescents and adult subjects with moderate facial acne who used sandalwood oil saw an improvement in their symptoms without any side effects (1).
Data from various studies state that sandalwood oil is well tolerated and safe. The oil is now being manufactured in compliance with the current Good Manufacturing Practices (1).
3. May Stimulate Hair Growth
Sandalwood oil was found to reduce the number of mast cells in mice studies. These cells are distributed around the hair follicles and could be responsible for shortening the hair growth stage (5). The oil could also promote hair growth in mice (5).
Researchers from the University of Manchester found that a sandalwood odorant could stimulate a certain receptor (called OR2AT4) in the body, which may prolong hair growth (6). More studies are needed to understand how well this odorant promotes hair growth in humans.
4. May Promote Sleep
Santalol, an active component of the oil, helps reduce the total waking time and increases the total non-rapid eye movement (NREM) phase of sleep (7).
Santalol is absorbed into the blood via the respiratory mucosa and is hence effective in promoting sleep. The essential oil can help individuals who have trouble falling asleep (7).
5. May Reduce Anxiety
Aromatherapy using sandalwood oil is effective in reducing anxiety. In studies, sandalwood oil (along with other oils) could reduce anxiety in women who were undergoing breast biopsies and in palliative care patients (8), (9).
Though the results seemed to support the idea that sandalwood oil may reduce anxiety, more large-scale studies are warranted (9).
6. May Fight Inflammation
Sandalwood oil inhibits oxidative enzymes and protects against oxidative stress. As per research, the oil suppresses the production of several pro-inflammatory chemokines and cytokines (compounds produced during inflammation) (1).
7. May Treat Urinary Tract Infections
Sandalwood oil also possesses antipyretic, antiseptic, and diuretic properties and can be effective in treating diseases of the urinary tract (10).
It is also believed that sandalwood oil may have a disinfecting action that treats infections of the urinary tract. However, more research is warranted here.
8. Could Act As An Antiseptic Agent
Sandalwood oil has antiseptic properties. It could be effective in the treatment of bronchitis, cystitis, and dysuria (10).
As it is a potent antiseptic and astringent, it may be used to treat inflammatory skin disorders like psoriasis (11).
9. May Boost Memory
Sandalwood essential oil can be used to promote mental clarity and boost memory (12).
A study conducted using mouse models has demonstrated significant improvement in learning and memory following the use of the essential oil. This was especially true during the growth spurt period (13).
10. May Control Blood Pressure Levels
In a study, different types of sandalwood essential oils could significantly reduce systolic blood pressure. The oil, along with other essential oils, could help in the recovery from stress (14).
Some research shows that a specific type of sandalwood powder contains mildly sedative ganglionic blockers or hypotensive agents that may help lower blood pressure (12).
11. Could Reduce Stress
Aromatherapy using essential oils has been effective in reducing stress.
Researchers investigating the physiological effects of sandalwood essential oil on human beings found that the oil could alleviate the physiological reactions to stress. The oil was also found to ease recovery after being exposed to stress (14).
12. May Help Relieve Menopause Symptoms
Essential oils have specific properties that ease and balance menopausal symptoms. Sandalwood oil contains sesquiterpenols that calm your nervous system down – and this might help ease menopausal symptoms like hot flashes (15).
In clinical studies, the oil has also been found to offer relaxing properties (15).
13. May Reduce Body Odor
There is little research here. Some reports suggest that the delightful aroma of sandalwood powder may help rid of body odor that could come from excessive sweating (3).
The oil may also alleviate unpleasant body odor, though research is limited. It is valued highly for its fragrant heartwood and is used in perfumes for its excellent fixative properties (3).
Insufficient Evidence For
14. May Help Relieve Stomach Issues
Sandalwood essential oil is believed to have been used in Chinese medicine to treat stomach pain and vomiting. It is thought that the antiviral and antibacterial activities of the oil help fight against Helicobacter pylori (the leading cause of stomach ulcers).
15. May Boost Immunity
Aromatherapy with essential oils like that of sandalwood is thought to boost your immunity by prompting your body to heal itself. Anecdotal evidence suggests that the oil promotes white blood cell production, fights microorganisms, and also improves immune responses in your body. However, more research is warranted in this aspect.
