What is Coleus graveolens? Coleus graveolens is a small, strongly scented shrub native to Australia. It sits in the mint family. Older books and labels call it Plectranthus graveolens. The leaves give off a sharp smell when crushed. The plant turns up in lists of Australian medicinal plants. Written records of how it was actually used are very thin. Here is the honest verdict first. No human trials have tested this plant for any health use. Traditional use tells you people reached for a plant; it does not prove the plant works, and it does not prove the plant is safe. One point matters more than any claim on this page. The "Coleus" sold in capsules is almost always a different plant, Coleus forskohlii. That species is the source of forskolin. Studies on it say nothing about Coleus graveolens. How does Coleus graveolens work? No one has published a worked-out mechanism for this plant. That is the plain state of things. Mint family plants usually carry volatile oils. These oils smell strong and can irritate skin. That is a general trait of the family, not a tested action of this species. In lab tests, oils from related Coleus and Plectranthus species slow the growth of some bacteria and fungi. Those tests used other plants, in dishes, not people. You cannot carry that result across to Coleus graveolens. So any claim you read about how this plant acts in the body is guesswork. Treat it that way. What forms does Coleus graveolens come in? This is not a mainstream supplement. You will not find a standard capsule of it. Forms it may turn up in: - The fresh or dried leaf, in a garden or bush setting. - A crushed leaf used on the skin, in past practice. - A steam or wash made from leaves, in past practice. - A garden plant sold by native plant nurseries. If a product label says only "Coleus" or "Coleus extract", it is most likely Coleus forskohlii. Check the full botanical name before you assume otherwise. Where it comes from: The plant appears in Australian records as a scented bush used by local people and later noted by settlers. Such records usually describe a crushed leaf or a steam, not a measured dose. Aromatic plants in Australia were often used for stuffy noses, sore skin and as a wash. Coleus graveolens is grouped with them mainly because it smells strong. The written record is thin, scattered, and rarely species-specific. Common names were shared across several plants. That makes old accounts hard to pin to this exact species. This history is set down here as background. It is not a method to copy at home.

Helps

What does Coleus graveolens help with? Blocked nose and chest congestion (traditional use only): Strong-smelling leaves were used as a steam or inhaled scent. That is the claim. There are no trials in people for this plant. A sharp scent can make breathing feel easier for a few minutes. That feeling is not the same as clearing an infection. Minor skin complaints, as a wash (traditional use only): Crushed leaves and leaf washes were applied to skin in past practice. No human study supports this. In lab dishes, oils from related species slow some bacteria. Whether anything similar happens on real skin has not been shown. Aromatic plant oils can also irritate skin or cause a rash. Insect repellent use (traditional use only): Scented mint family plants were often rubbed on skin or burned to keep insects away. Some related plant oils repel mosquitoes in lab tests. No published test covers this species. Do not rely on it where mosquito-borne illness is a risk. General "tonic" or wellbeing claims (unsupported): Some sellers borrow claims made for Coleus forskohlii, such as weight loss or blood pressure support. Those claims do not transfer. They were studied in a different plant, and even there the results are mixed. Nothing supports them for Coleus graveolens.

What is Coleus graveolens?

Coleus graveolens is a small, strongly scented shrub native to Australia. It sits in the mint family. Older books and labels call it Plectranthus graveolens.

The leaves give off a sharp smell when crushed. The plant turns up in lists of Australian medicinal plants. Written records of how it was actually used are very thin.

Here is the honest verdict first. No human trials have tested this plant for any health use. Traditional use tells you people reached for a plant; it does not prove the plant works, and it does not prove the plant is safe.

One point matters more than any claim on this page. The "Coleus" sold in capsules is almost always a different plant, Coleus forskohlii.

That species is the source of forskolin. Studies on it say nothing about Coleus graveolens.

How does Coleus graveolens work?

No one has published a worked-out mechanism for this plant. That is the plain state of things.

Mint family plants usually carry volatile oils. These oils smell strong and can irritate skin. That is a general trait of the family, not a tested action of this species.

In lab tests, oils from related Coleus and Plectranthus species slow the growth of some bacteria and fungi. Those tests used other plants, in dishes, not people. You cannot carry that result across to Coleus graveolens.

So any claim you read about how this plant acts in the body is guesswork. Treat it that way.

What forms does Coleus graveolens come in?

This is not a mainstream supplement. You will not find a standard capsule of it.

Forms it may turn up in:

- The fresh or dried leaf, in a garden or bush setting. - A crushed leaf used on the skin, in past practice.

- A steam or wash made from leaves, in past practice. - A garden plant sold by native plant nurseries.

If a product label says only "Coleus" or "Coleus extract", it is most likely Coleus forskohlii. Check the full botanical name before you assume otherwise.

Who should avoid Coleus graveolens?

  • Do not use it if you are pregnant or trying to become pregnant.
  • Do not use it if you are breastfeeding.
  • Never give it to a baby or a child.
  • Never swallow the essential oil, and never put it in a nebuliser.
  • Do not use it if you are allergic to mint family plants, such as basil, mint, sage or oregano.
  • Avoid it if you have asthma or a long-term lung disease such as COPD (a long-term lung disease), because strong steam can trigger an attack.
  • Do not use it in place of your inhaler, antibiotics or any prescribed medicine.
  • Avoid it if you have liver or kidney disease, since nothing is known about how your body clears it.
  • Do not use it in the two weeks before planned surgery.
  • Do not treat it as a swap for a Coleus forskohlii product, and do not use a forskohlii dose for this plant.
  • Do not pick and use any wild plant unless an expert has confirmed the species.

When should you see a doctor?

Stop using it and see a doctor if any of the following happen:

- A rash, blistering or burning where it touched your skin. - Wheezing, tight chest or a cough that will not settle. - Swelling of the lips, tongue or face. - Vomiting, belly pain or dark urine after swallowing any part of it. - Yellow skin or eyes.

Call emergency services for trouble breathing or throat swelling. Go straight to hospital if a child has eaten any part of the plant. Take a photo or a sample of the plant with you.

Is Coleus graveolens legal where you live?

In Australia, this plant is not approved as a medicine by the Therapeutic Goods Administration. It is not a listed food either. In the UK, the US and the EU it has no approved medical use and no food history, so any product making health claims is sold outside the rules.
