苦橙是a plant. The peel, flower, leaf, fruit, and fruit juice are used to make medicine. Bitter orange oil is made from the peel.
Bitter orange, both taken by mouth and applied to the skin, has many uses. But so far, science has shown only that the oil, when applied to the skin, might be effective for treatment of fungal skin infections (ringworm, jock itch, and athlete's foot).
Bitter orange peel is also used to improve appetite, and, in surprising contrast, it is also used for weight loss. Other uses for the fruit and peel are upset stomach, nasal congestion, and chronic fatigue syndrome (CFS).
The bitter orange flower and bitter orange oil are used for gastrointestinal (GI) disorders including ulcers in the intestine, constipation, diarrhea, blood in feces, drooping (prolapsed) anus or rectum, and intestinal gas. These parts of the bitter orange plant are also used for regulating fat levels in the blood, lowering blood sugar in people with diabetes, stimulating the heart and circulation, "blood purification," disorders of liver and gallbladder, kidney and bladder diseases, and as a sedative for sleep disorders.
Some people use bitter orange flower and its oil for general feebleness, "tired blood" (anemia), impurities of the skin, hair loss, cancer, frostbite, and as a tonic.
Bitter orange peel is applied to the skin for swelling (inflammation) of the eyelid and its lining, as well as the retina in the eye. It is also used for bleeding from the retina, exhaustion accompanying colds, headaches, nerve pain, muscular pain, joint pain, bruises, swelling of the veins (phlebitis), and bed sores.
In aromatherapy, the essential oil of bitter orange is applied to the skin and also inhaled as a painkiller.
In foods, bitter orange oil is used as a flavoring agent. The fruit is used for making marmalades and liqueurs such as Triple Sec, Grand Marnier, Cointreau, and Curacao. Because the fruit is so sour and bitter, it is rarely eaten, except in Iran and Mexico. The dried peel of the fruit is also used as a seasoning.
In manufacturing, bitter orange oil is used in pharmaceuticals, cosmetics, and soaps.
In Asian medicine, the entire dried unripe fruit is used primarily for digestive disorders.
苦橙经常用于“ephedra-free”products since the FDA banned ephedra in 2004 for serious side effects on the heart. Bitter orange and caffeine, a frequent combination in weight loss and bodybuilding products, can cause high blood pressure and increased heart rate in healthy adults with otherwise normal blood pressure. There is no evidence to suggest that bitter orange is any safer than ephedra.
Bitter orange (synephrine) is considered a banned substance by the National Collegiate Athletic Association (NCAA).
Before taking bitter orange, talk with your healthcare professional if you take any medications. It can interact with many drugs.
How does it work?
Bitter orange has many chemicals that affect the nervous system. The concentration and effect of these chemicals can change depending on the part of the plant and the method used for preparation. These chemicals can squeeze blood vessels, increase blood pressure, and cause the heart to beat faster.

苦橙是LIKELY SAFEfor children and adults when taken in the amounts found in food. Bitter orange essential oil isPOSSIBLY SAFEwhen applied to the skin or inhaled as aromatherapy.
But bitter orange isPOSSIBLY UNSAFEwhen taken as a supplement for a medical purpose such as weight loss. Bitter orange, particularly when taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for high blood pressure, fainting, heart attack, stroke, and other severe side effects.
There are reports that bitter orange can trigger headaches, including migraine and cluster headaches, in some people.
Bitter orange can cause sensitivity to the sun. Wear sunblock outside, especially if you are light-skinned.
QUESTION
Ringworm is caused by a fungus.See AnswerDiabetes: Some evidence suggests that bitter orange may interfere with blood sugar control in patients with type 2 diabetes. Use with caution and monitor blood sugar levels closely.
High blood pressure: Some studies suggest that bitter orange, especially in combination with caffeine, can increase blood pressure in healthy people. Other studies have found no such blood pressure elevation. To date, there haven't been any studies looking at the effect of bitter orange on blood pressure in people who already have high blood pressure. Don't take a chance. Avoid using bitter orange, especially in combination with stimulants such as caffeine, if you have high blood pressure.
Glaucoma: Bitter orange might worsen glaucoma. Avoid using it if you have this condition.
Heart disease: Using bitter orange, especially in combination with caffeine or other stimulants, might increase the risk of serious side effects in people with a particular heart problem called "long QT interval syndrome" (named after the wave pattern made by a electrocardiogram).
Irregular heartbeat (heart arrhythmia): Some studies suggest that bitter orange, especially in combination with caffeine, can increase heart rate in healthy people. Other studies have found no such effect on heart rate. So far, there have been no studies of the effect of bitter orange on people who have an irregular heartbeat. Avoid using bitter orange, especially in combination with stimulants such as caffeine, if you have an irregular heartbeat.
Surgery: Bitter orange acts like a stimulant, so it might interfere with surgery by increasing heart rate and blood pressure. Stop taking bitter orange at least 2 weeks before a scheduled surgery.
Medications for depression (MAOIs)Interaction Rating:MajorDo not take this combination.
Bitter orange contains chemicals that stimulate the body. Some medications used for depression can increase these chemicals. Taking bitter orange with these medications used for depression might cause serious side effects including fast heartbeat, high blood pressure, seizures, nervousness, and others.
