The health benefits of ginger essential oil are nearly identical to the medicinal health benefits of fresh ginger; in fact, the most potent form of ginger is the essential oil because it contains the highest levels of gingerol. The essential oil is the best way to use ginger as medicine. It can be taken internally to treat health conditions or rubbed topically with a carrier oil on an area of pain.

Benefits Include:

Stomach & Food Poisoning: Ginger root and ginger oil are often used for upset stomachs and can be used to help treat food poisoning. It is one of the best remedies for indigestion, stomach ache, dyspepsia, colic, spasms, diarrhea, flatulence and other stomach and bowel related problems. Ginger or ginger oil is often added to recipes as it helps in improving digestion. Ginger tea is also used for relieving stomach problems. 

Nausea and Vomiting: Research has shown that ginger root and its oil are also effective against nausea, motion sickness and vomiting. Use of ginger may also result in a reduction of pregnancy-related vomiting in women.

Heals Infections: Ginger essential oil is an antiseptic; it kills infections that are caused by microorganisms and bacteria. This includes intestinal infections, bacterial dysentery and food poisoning.

Ginger oil is effective against Malaria, for example, a mosquito-    borne infectious disease. Malaria causes symptoms that typically include fever, fatigue, vomiting and headaches; in severe cases it    can cause yellow skin, seizures, coma or death.                            

High Levels of Antioxidants: Ginger root contains a very high level of total antioxidants. Antioxidants are substances that help prevent certain types of cell damage, especially those caused by oxidation; oxidative damage plays a major role in disease today and has been linked to health conditions like heart disease, cancer and dementia.

 

   Respiratory disorders: Since ginger root and ginger oil are   both      good expectorants, they are effective in treating various                      respiratory problems such as cold, cough, flu, asthma, bronchitis        and breathlessness. Ginger is very effective in removing mucus          from the throat and lungs, so it is often added to tea in India. The        health benefits of honey and ginger in treating respiratory problems is well known.

Inflammation and Pain: Ginger is analgesic in nature and reduces the pain caused by muscle aches, arthritis, rheumatic conditions, headaches, and migraines. Ginger oil or  ginger paste is often topically massaged on aching muscles to remove muscle strain. It is further believed that regular use of ginger leads to the reduction of prostaglandins, which are the compounds associated with pain. Therefore, ginger helps in pain relief. Recently, a few Chinese researchers have reported that ginger can be very effective in treating inflammation of the testicles.

Menstruation Problems: Irregular and painful menstrual discharges can be treated with ginger.

Heart ailments: In China, it is strongly believed that ginger boosts and strengthens your heart health. Preliminary research has indicated that ginger may be helpful in reducing cholesterol levels and preventing blood clots. With reduced cholesterol levels and blood clotting, the chance of blood vessel blockage decreases, thereby reducing the incidences of heart attacks and strokes.

Improves Liver Function: Because of ginger essential oil’s antioxidant potential and hepatoprotective activity, a study published in the Journal of Agricultural and Food Chemistry measured its effectiveness in treating alcoholic fatty liver disease, which is significantly associated with hepatic cirrhosis and liver cancer.

Stress: Ginger oil, being an essential oil, is stimulating and therefore relieves depression, mental stress, exhaustion, dizziness, restlessness and anxiety.

Impotency: Ginger is helpful for male health as well. Since ginger root and its oil are aphrodisiac in nature, it is effective in eliminating impotency and preventing premature ejaculation.

Kidney: It is also believed that ginger root juice is able to dissolve kidney stones.

Hair care: Ginger is useful for hair care as well. Ginger juice is useful in controlling dandruff.

Natural Aphrodisiac: Ginger essential oil increases sexual desire; it addresses issues such as impotence and loss of libido. Impotence, also known as erectile dysfunction, is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse; the causes may be physiological or psychological. Because of its warming and stimulating properties, this ginger essential oil serves as an effective and natural aphrodisiac, as well as a natural remedy for impotence. It also helps to relieve stress and brings forth feelings of courage and self-awareness — eliminating self-doubt and fear.

Cancer: According to the American Cancer Society, preliminary research on animals has shown that ginger may be useful in treating cancer.

It should be noted that ginger oil is very strong and should therefore be used carefully and sparingly.

Ginger oil blends well with many other essential oils including lemon, cedarwood, lime, eucalyptus, frankincense, geranium, rosemary, sandalwood, patchouli, myrtle, bergamot, rosewood, neroli, orange and ylang-ylang.
