Star Anise

Star anise (Illicium verum), or Chinese anise, is an important spice in Asian cuisine that lends dishes a sweet licorice-like taste. It is one of the ingredients of the popular five-spice powder that pairs well with many savory dishes and confectioneries. Star anise’s name illicium means alluring because of its rich and warm flavor, as well as its pleasant aroma. Aside from food, star anise is also used in some alcoholic and non-alcoholic beverages. In the cosmetic industry, star anise is an ingredient added to toothpaste, soaps, perfumes, and aromatherapy products.

Star anise is often confused with anise, but these two are genetically different plants. They do taste similar. However, star anise has a slightly bitter taste than anise. These two spices are not used as a replacement for the other. Anise is common in Western and Greek cuisines, while star anise is a staple in Asian cooking.

For more than three centuries, the star anise is a prominent spice and medicine in South China and Vietnam. It was enjoyed in many countries in Asia and discovered by an English sailor in the Philippines in the late 1600s. The sailor, Sir Thomas Cavendish, then brought the spice back to Europe. Its origin was traced back to China and soon after, it was traded from China to Russia and Germany.

Where Star Anise Is Found

The star anise is indigenous to Southern China and grows abundantly in tropical climates. They are also called badian, which means eight horns due to their shape. Star anise trees are abundant in damp woodlands and along streams and riverbanks. This fast-growing evergreen tree is frost delicate. Thus, they are not suitable for growing in areas with freezing winter unless tended in a greenhouse.

How To Identify Star Anise

Star anise is known for its distinctive star-like, aromatic dried fruits. This tropical starry spice grows on medium-sized trees that are sometimes utilized as hedges in the garden.

But when it starts to blossom, you will have bountiful produce of star anise for cooking and medicine.

Leaves. The aromatic leaves of the star anise are large, lanced-shaped, and olive green in color. The broad leaves measure around 10 to 15 cm long and 2.5 to 5 cm across. They are alternate, simple, and are clustered at the end of the branches.

Flowers. Star anise flowers are white-pink to dark red or greenish-yellow that usually bloom in the sixth year. These flowers are also large at about 1 to 1.5 cm in diameter and are solitary and bisexual. It is made up of multiple whorled petals forming into a cup shape.

Star Anise- leaves and fruitFruits. Before the star-shaped fruit ripens out to its brown form, star anise fruits are green. It has six to eight carpels that form the star shape, each containing a seed. Each carpel is boat-shaped and about 10 mm long.

Chinese star anise is the spice that is used either whole or ground. It is known by many names like badian, aniseed stars, eight-horn, and eight-horned anise. The Chinese star anise is often mistaken for the Japanese star anise because of its identical appearance. However, Japanese star anise (Illicium anisatum) is highly toxic. Thus, it is not used in either folk remedies or food. Their only distinctive difference is their aroma since the Japanese star anise has a slightly milder fragrance.

How To Grow Star Anise

The star anise tree proliferates in tropical and subtropical climates. Some gardeners consider it a delicate plant because they are not very adaptable to frost. They will only flourish in USDA zones 8 to 10. In a conducive environment, star anise is highly adaptable and can grow into a sturdy plant.

Propagation of the star anise can be done through planting its cutting or starting them from seeds. Cutting is by far the most successful and speedy way of propagation as the plant easily regrow its roots. But if you do not have an existing plant, you can start with seeds though it needs a bit more patience.

In some local nurseries, you may find a full-grown star anise plant. If available, choose the healthiest and most stable star anise growth.

Propagation by Seeds

Growing star anise from seeds needs the right temperature to facilitate its germination. Sow your star anise seeds in a container or directly in the garden with a temperature ideally at 65 to 70°F. Keep the soil moist but not too soggy to prevent mildew and root rots.

Choose your seeds for planting carefully by putting them in a container of water. The seeds that sink are viable for planting, so discard all that floats up the surface.

Plant your star anise seeds at one seed per container. Make sure to poke drainage holes at the bottom to prevent it from getting waterlogged. The germination period of star anise seeds may take 4 to 8 weeks.

Propagation by Cutting

Propagate your existing star anise plant by removing a four-inch section of its branch. Plant it in sterile soil made from a mixture of sand, peat, and perlite. Wait for the cutting to root and keep the plant healthy. Transplant the new plant in the spring or wet season.

Plant Care and Maintenance

Star anise, when established, is highly adaptable. They can grow even in dappled shade and partial sun as long as they are not exposed to cold and dry wind. As the plant grows, you will need to prune it regularly for it to encourage bushier foliage.

The requirements for growing star anise are simple:

  • Full sun with dappled afternoon shade
  • Moist but not soggy soil
  • An inch of water per week
  • Loamy soil with a pH level between 6.0 to 7.5
  • Aged manure and rich compost

How To Harvest Star Anise

In favorable conditions, it will take your star anise plant at least six years to bear its first flower and fruits. The star-shaped fruits while they are still green and the pods are rounded. Star anise fruits will only change into their popular wooden and rusty color when they are thoroughly dried. They are ready for harvest when the seeds already have a distinctive aroma when pinched.

When they are ready for harvest, you will need to remove the fruits individually using garden shears. Dry the stars thoroughly under the sun until they turn reddish-brown. You may choose to leave the seeds in the pod or remove them before storing them in an airtight container. Stored star anise can last up to two years before losing its distinctive fragrance. Once it does, these seeds are no longer useful for cooking or medicine.

Ive heard that it also contains Suramin, which is apparently effective for treating covid, the effects of shedding, etc.

Mike Adams have talked about how to prepare shikimic acid from star anis with an expresso machine. Suramin is the name of a pharma medicin for sleep sickness. But this shikimic acid that you can get from Star anis drink in this way make something similar.

Suramin is being studied as it helps with autism. I would imagine there is something natural to cure autism as well. God bless and may all be healed from the earth and not a pharmacy!

Do you have a Star Anise tincture?

Hello Sandra,

Thank you for your comment.
You can make a Star Anise tincture using 200 ml Vodka, 1-2 tbsp Anise Seeds and 4-8 Star Anise.

People use star anise tincture to treat respiratory infections, lung swelling, cough, bronchitis, influenza, swine flu, and bird flu. It is also used to treat digestive issues such as upset stomach, gas, loss of appetite, and colic in babies.

Many blessings and good health!

It would appear that star anise is good for a lot of things I didn’t know about. I recently bought a huge bag of it for Asian cooking, which I’ve been doing at home more lately, and I was thinking about how my bag contains way too much to ever use by myself. But thanks to your email referencing it and having read more about it, I think it was a really great buy, and I’ll be using it for all kinds of other things, especially with milk and molasses! 😋

How would you use the tincture?

I’m trying to find the star anise plant, or even some fresh seeds for sprouting. I can grow it outside all year round in south florida, but no one seems to have it!! Where can I buy it, online or in person? Help please!!

We combine a little bit of star anise (I grind it slightly in a food processor or coffee grinder for a few pulses, not into powder, just enough to expose more of it) with chamomile flowers and lemon balm. My partner has ADHD and this helps him sleep; he also has acid reflux, so the star anise helps calm his belching. Chamomile usually knocks me out so I’m useless for days at a time, though this particular combination helps me sleep well for several hours and still be functional. Star anise seems to make a positive difference for our entire household.
