HistoryThere is not much recorded historical medicinal use of the bitter orange, although the English herbalist Gerard recommended the hot and bitter juice of citrus fruits against worms and the stings of scorpions.
Bontanical Name: Citrus aurantium var. Amara
Method of Extraction: Steam distillation
Plant Part:Leaves/ Branches
Vaporisation: Add 5-10 drops of essential oil into warm water by using diffuser.
Massage: Add 4-5 drops of essential oil into 10ml of carrier oil for facial or body massage or as a home-made body oil after shower. It is very good for muscular and spiritual relaxation.
Bathing: Add 8-10 drops for a full bath. It can stimulates blood circulation and is ideal way to relax.
Inhalation: Add 3-5 drops of essential oil into a bowl of steaming water. Place a towel over the head, close your eyes and inhale deeply. It can help to relieve physical and mental stress, especially headache and respiratory system problems.
Clay mask (Cleansing and Whitening): Add 1-2 drops of essential oils to the mixtures of floral water and clay mask.
Personal skin care product (e.g Shampoo，Bath Gel，Facial cream etc.): Add 4-5drops of essential oils to your own skin care products, create the unique personalised skin care products.
Perfume: Add 4-5 drops of essential oils and 4-10 drops of solubiliser into 10ml water to create your own personalised perfume.
Blending Base Measurement:
1% Essential oil in (5/10/30/50/100)mL = (1/2/6/10/20) drops per volume of essential oil respectively
2% Essential oil in (5/10/30/50/100)mL = (2/4/12/20/40) drops per volume of essential oil respectively
2.5% Essential oil in (5/10/30/50/100)mL = (3/5/15/25/30) drops per volume of essential oil respectively
Eye care = 0.5% Face = 1% - 2% Adult full body = 2% - 2.5%
*Remarks: Thin oil can apply onto skin directly. Thick oil is sticky, diluted with thin oil will be better
Proportion: Thick Oil 10-20％Thin Oil 80-90％
Antioxidant Activity An investigation was carried out in order to estimate the biochemical changes occurring in bitter orange (Citrus aurantium L.) leaves in response to melatonin (MEL), gibberellic acid (GA) and salicylic acid (SA) treatments. It could be concluded that 15 mM MEL, 1.44 mM GA and 1 mM SA increased the total phenolic and flavonoid content of bitter orange leaves, as well as their antioxidant activity. (Sarrou et al., 2015) Antibacterial The results of the micro-dilution assay presented petitgrain oils have the most antibacterial and antifungal propertyIn conclusion, demonstrating that essential oils of C. aurantium leaf have antimicrobial activities. The high in vitro antimicrobial activity of bitter orange leaf oil could be attributed to the presence of high amounts of oxygenated monoterpenes such as linalool, alpha terpineol, and linalyl acetate. Statistics showed it is effective against Staphylococcus aureus (cause a range of illnesses: from minor skin infections, such as pimples, impetigo, boils, cellulitis, folliculitis, carbuncles, scalded skin syndrome, and abscesses, to life-threatening diseases such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome, bacteremia, and sepsis), Streptococcus Faecalis (cause a variety of infections, including endocarditis, urinary tract infections, prostatitis, intra-abdominal infection, cellulitis, and wound infection as well as concurrent bacteremia) and Salmonella Typhi (bacteria that infect the intestinal tract and the blood, causes typhoid fever).
