Star anise oil has had many uses, but these days it is mostly used to combat bacterial, viral, and fungal infections. Its ability to comprehensively protect our health makes it incredibly popular in many medical systems – including modern western medicine.

A member of the Illiciaceae family, star anise oil is extracted via steam distillation from the dried, ripe fruit of the evergreen tree, native to Southeast Asia. Each fruit contains five to thirteen little seed pockets attached in the shape of a star. This fixture is what gives the spice its name.

Is star anise oil good for the flu?

One of the main agents used for protection against and treatment of the influenza virus is a chemical component called shikimic acid.

Star anise has a very high level of shikimic acid content and a showed that the fruit is actually the primary source of shikimic acid in pharmaceuticals.

Does star anise essential oil have antifungal properties?

Star anise contains a significant amount of a component called anethole – which can also be found in aniseed and is responsible for the oil’s distinct scent.

The anethole component has strong antifungal properties and can be instrumental in protecting us from fungal infections. In fact, a found that anethole may help star anise inhibit the growth of infectious fungi in humans.

Can star anise combat bacterial infections?

Using star anise oil to relieve stress

Star anise essential oil is considered a natural sedative, meaning it can slow our brain activity, calm our minds, and relieve our stress when inhaled.

Sedatives can make for a useful aid against symptoms of anxiety, so using star anise as a natural alternative could be a viable option.

The calming properties of star anise oil may be attributed to the presence of the component nerolidol, which is a known sedative.

Star anise essential oil for digestion and pain

Some sources claim that star anise may also function as an anti-inflammatory and can effectively stimulate blood circulation to alleviate pain in certain regions of the body.

Using star anise oil to help treat muscular or joint pain could be an effective natural alternative to common pain killers.

While essential oils should never be taken internally, topical application of star anise combined with a carrier oil can be a useful remedy against digestive issues and their related pains.

How to use Star Anise Essential Oil


Like the sweet and faintly spicy scent of liquorice? Then star anise is a fantastic choice for diffusing around your home – particularly during the winter months.

This inviting scent is incredibly useful for protection against respiratory illnesses, as well as any airborne bacteria.

If you’re struggling to switch your mind off and settle into sleep, the sedative qualities of star anise may also be a good choice for diffusing around your bedroom.


If you don’t have a diffuser to hand, or if you simply prefer enjoying your essential oils in conjunction with another relaxing activity, then sprinkling some star anise into your bath may be the ideal choice for you.

Using star anise in the bath is a great way to experience the oil’s sedative abilities - particularly if you are bathing before bed – and can also help soothe sore muscles or joints.


Combine star anise with a carrier oil for a restorative at-home massage with good anti-inflammatory benefits.

The stimulating properties of star anise can help to relieve pain caused by digestive issues and inflammation by increasing blood flow in the body – so performing a massage on yourself or a loved one can help push these benefits even further.

Remember to always perform a patch test before applying essential oils on the skin and be sure to dilute with a carrier oil before use.


As star anise is an antibacterial, it can be used to help clean or top-up surfaces to prevent harmful strains of bacteria.

Combine a few drops of star anise oil with water and an emulsifier (like dish soap) in a spray bottle and use at will.
