What is Petitgrain?
Petitgrain comes from the bitter orange tree, which is an evergreen featuring a smooth grayish trunk, thorns, fragrant white waxy flowers, yellow stamens, and small orange fruits that are darker and smaller than sweet oranges.
The tree produces three kinds of oils:
- Bitter orange - also known as C. bigaradia, C. vulgaris, and Seville orange. The oil is produced through cold expression of the rind of the fruit and is sometimes called sour orange bigarade.
- Petitgrain - also known as C. bigaradia. The oil is produced through steam distillation of the leaves and twigs. It is commonly called petitgrain bigarade or petitgrain Paraguay oil.
- Neroli - also known botanically as C. bigaradia, or C. vulgaris, while the oil is often aptly called orange blossom, orange flower, or neroli bigarade. The rather expensive neroli essential oil is steam distilled from the freshly picked flower of the tree.
While these oils share some of the same qualities, they are also very different and are a perfect example of why it is imperative to pay attention to what you are buying and using.
For instance, even though these three oils come from the same tree, bitter orange oil is the least recommended by aromatherapists, as sweet orange (Citrus aurantium) is preferred for use.
If you want the highest-quality petitgrain oil, look for those that come from France. That being said, Haiti, North Africa, and Paraguay also produce good petitgrain oils.
There are other "petitgrain" oils on the market, too. One comes from the leaves, twigs, and unripe fruit of bergamot (C. bergamia), lemon (C. limon), mandarin (C. reticulata), and sweet orange (C. aurantium) trees.
Furthermore, there is a type of petitgrain produced from a hybrid of two different orange trees, C. aurantium, and C. sinensis. This is usually produced in Paraguay.
In the past, petitgrain was produced from unripe oranges when they were tiny and green, which is how it got the moniker of "petitgrain." It was one of the first ingredients used in eau de cologne and records show it was being distilled as early as 1694. 
When you are shopping for petitgrain essential oil, look for a colorless or pale yellow liquid. Be sure to pay attention to the botanical name.
There are no known contraindications for petitgrain.
Petitgrain blends well with other citrus oils, black pepper (Piper nigrum), cardamom (Elettaria cardamomum), clary sage (Salvia sclarea), Cypress (Cupressus sempervirens), ginger (Zingiber officinale), patchouli (Pogostemon cablin), vetiver (Vetiveria zizanioides), and many more.

When a woman is pregnant, her body is prepared for nine months of gestation. If this ends prematurely, the hormones fluctuate wildly and can cause significant emotional turmoil.
Petitgrain is a wonderful oil for this situation. It can help with the mood swings and emotional instability. It is likewise useful for postnatal depression.

Petitgrain Essential Oil Research, Facts, and Studies
There are numerous studies on petitgrain oil that can be found. Some of the more interesting and useful ones are:
Uses in Dermatology
According to a research study produced in Evidence-based Complementary and Alternative Medicine (eCAM) in 2017, there are a number of dermatological applications for petitgrain essential oil as listed in aromatherapy literature:
- Bacterial infections
- Balances sebum in greasy and oily skin

The research also states that the oil shows efficacy against:
- Skin problems associated with gram-negative pathogens

Singlet Oxygen Scavenging
Oxygen is usually a good thing and something we all need to survive. However, singlet oxygen (1O2) is a reactive oxygen species (ROS) and is a highly active form. When produced on the skin after exposure to ultraviolet rays, it starts attacking cells.
In a study from 2008 published in the Journal of Clinical Biochemistry and Nutrition, petitgrain from France showed 100% scavenging activity against this dangerous oxygen at 0.1%, 0.4–2%. At 0.2% concentration, the scavenging efficacy was 92%. 
Petitgrain is a versatile essential oil to keep on hand. There are no known contraindications of this oil, although any oil should be skin-tested before using, especially on individuals with sensitive skin.
Because there are three oils that come from the same tree, make sure you purchase the correct one. Always do your research.
