Medical Cannabis, CBD Oil and Hemp Extracts: What Do These Terms Mean?

A plain-English guide to CBD oil, hemp oil, cannabinoids, extracts and Australian cannabis terminology

Every day, more people are hearing about CBD oil, medicinal cannabis, hemp extracts, full-spectrum oils, terpenes and the endocannabinoid system.

That is exciting, because the public conversation around hemp and cannabis has moved a long way beyond old stigma. But it can also be confusing. The same words are often used in different ways, and products that sound similar may sit in completely different categories.

CBD oil is not the same as hemp seed oil. Hemp extract is not always the same as CBD oil. Medicinal cannabis oil is different again. And in Australia, the legal landscape around CBD and cannabis-derived products is still more tightly regulated than many international markets.

This guide explains the key terms in plain English so you can better understand what people mean when they talk about CBD oil, hemp oil, cannabis extracts and medicinal cannabis.

Important Information
Made In Hemp is licensed to grow industrial hemp in Australia. Current Australian legislation limits what we can say, promote, or supply online in relation to medicinal cannabis, CBD and cannabis-derived products.

Quick glossary

If you are new to this space, these are the terms you are most likely to come across:

What is CBD oil?

CBD oil usually refers to an oil-based product that contains cannabidiol, or CBD.

CBD is one of the best-known cannabinoids found in cannabis and hemp plants. It is non-intoxicating, which means it does not create the “high” associated with THC. This is one of the reasons CBD has become such a major part of the global cannabis, wellness and medicinal cannabis conversation.

CBD oil is usually made by extracting CBD-rich compounds from cannabis or hemp plant material and blending the extract into a carrier oil. Carrier oils may include MCT oil, olive oil, hemp seed oil or other suitable oils depending on the product.

In Australia, CBD products used for therapeutic purposes are regulated as medicines. Some CBD products fall under Schedule 4, meaning they are prescription-only medicines. A low-dose Schedule 3 pathway exists, but over-the-counter CBD products still need to be approved by the TGA and included on the Australian Register of Therapeutic Goods before they can be supplied through that pathway.

CBD oil in simple terms

CBD oil contains cannabidiol from a cannabis or hemp extract. It is not the same thing as hemp seed oil, and in Australia it sits in a different regulatory category when used or promoted for therapeutic purposes.

CBD oil is not the same as hemp seed oil

This is one of the biggest points of confusion.

Hemp seed oil is pressed from the seeds of the hemp plant. It is used in foods, skincare, body oils, face oils, balms, soaps and other everyday hemp products. It is valued for its fatty acid profile, nutrition and skin feel.

CBD oil contains cannabidiol from a cannabis or hemp extract. CBD is a cannabinoid, and cannabinoid products are regulated differently from ordinary hemp seed foods or hemp seed oil skincare.

The seed itself does not naturally contain meaningful levels of CBD or THC, because cannabinoids are mostly associated with the flowering tops, leaves and resinous parts of the plant rather than the seed.

So if a product says “hemp oil,” your next question should be: oil from which part of the plant?

Product Made from Contains CBD? Common category
Hemp seed oil Pressed hemp seeds No meaningful CBD or THC naturally present Food, skincare, body care, plant oil
CBD oil Cannabis or hemp extract blended into a carrier oil Yes, if properly labelled as a CBD product Cannabinoid product / medicinal cannabis context

What is medicinal cannabis oil?

Medicinal cannabis oil usually refers to a cannabis-based oil supplied for therapeutic use through medical pathways.

These products may contain CBD, THC or a combination of cannabinoids. They may also contain other minor cannabinoids or terpenes depending on the formulation.

In Australia, medicinal cannabis products are generally accessed through regulated medical pathways. This may involve a qualified health professional, prescription and pharmacy supply.

This is very different from buying hemp seed oil for food or using hemp seed oil in a face cream.

What are cannabinoids?

Cannabinoids are naturally occurring compounds found in the cannabis plant. CBD and THC are the best known, but they are not the only ones.

Other cannabinoids include CBG, CBN, CBC, THCV and CBDV. These are often called minor cannabinoids because they usually occur in smaller amounts, not because they are unimportant.

Cannabinoids are interesting because they can interact with the body’s endocannabinoid system — a natural signalling system involved in balance and regulation.

What is cannabidiol?

Cannabidiol is the full name for CBD.

CBD is non-intoxicating and is not associated with the cannabis “high” in the same way as THC. It has attracted strong interest from researchers, patients, wellness consumers and cannabis educators around the world.

CBD is often discussed in relation to calm, sleep, pain, inflammation, stress response and neurological research areas, but it should not be presented as a cure-all. Research is still developing, and personal medical decisions should be discussed with a qualified health professional.

CBD vs THC

CBD and THC are both cannabinoids, but they are experienced very differently.

CBD is non-intoxicating and does not create the “high” associated with cannabis.

THC is intoxicating and dose-sensitive. It is the cannabinoid most associated with the psychoactive effects of cannabis, but in medicinal cannabis conversations it also has a more nuanced role than old stigma suggests.

Some medicinal cannabis products contain CBD only. Others may contain THC, or a balanced ratio of CBD and THC. The most appropriate cannabinoid profile depends on the person, the product, the dose and the clinical context.

What is full-spectrum oil?

Full-spectrum oil is generally used to describe an extract that retains a broader range of naturally occurring compounds from the cannabis or hemp plant.

This may include cannabinoids, terpenes, flavonoids and other plant constituents depending on the product and how it is made.

Full-spectrum extracts are often discussed in relation to the entourage effect, but the term should still be backed by clear testing. A product labelled full spectrum should explain which cannabinoids are present, whether THC is detectable, and how much of each cannabinoid is included.

What is broad-spectrum oil?

Broad-spectrum oil is usually used to describe a refined extract that still contains multiple plant compounds.

In many CBD markets, broad spectrum often means a product contains a range of cannabinoids and terpenes, but has had THC removed or reduced. In practical formulation language, it may also refer to a cleaner, lighter or more neutral extract.

Because the term can be used differently, the label and certificate of analysis matter more than the marketing phrase.

What is CBD isolate?

CBD isolate is a purified form of cannabidiol.

Unlike full-spectrum or broad-spectrum extracts, an isolate contains one purified cannabinoid rather than a broader plant profile. It is often used where consistency, precision or a neutral taste is important.

That does not make isolate better or worse than other extract types. It simply makes it different.

What is the entourage effect?

The entourage effect is the idea that cannabinoids, terpenes and other cannabis compounds may work together to influence the overall character of a product.

This is one reason full-spectrum and broad-spectrum extracts are so interesting. Many researchers, formulators and patients are curious about whether a broader plant profile may feel different from a single isolated cannabinoid.

However, the entourage effect should be described carefully. It is a promising and widely discussed idea, not a guarantee that every full-spectrum product is automatically better for every person.

What are terpenes?

Terpenes are aromatic compounds found in many plants, including cannabis, hemp, lavender, citrus, rosemary and pine.

They help create the aroma and flavour of different cannabis varieties and plant extracts. Terpenes are one of the reasons two cannabis products with similar CBD or THC levels may still smell, taste or feel different.

Terpenes are also being studied as part of the wider whole-plant cannabis conversation, especially in relation to formulation, aroma, user experience and the entourage effect.

What are phenols and flavonoids?

Older cannabis education often used broad terms like phenols, phenolic compounds or flavonoids when describing plant chemistry.

In simple terms, these are plant compounds that can contribute to colour, flavour, antioxidant activity and the overall chemical profile of a plant. They are not the same thing as cannabinoids, and they should not be confused with CBD or THC.

For most customers, the key takeaway is simple: cannabis and hemp contain more than cannabinoids alone. The plant also contains terpenes, flavonoids and other compounds that may influence the overall extract profile.

What is decarboxylation?

Decarboxylation is a process where heat or time changes cannabinoids from their acidic forms into their more familiar active forms.

For example, cannabis plants naturally produce cannabinoid acids such as CBDA and THCA. Through decarboxylation, these can convert into CBD and THC.

This is one reason processing matters. Raw plant material, dried flower, heated extracts and finished oils may have different cannabinoid profiles depending on how they are handled.

Why laboratory analysis matters

Laboratory analysis is essential for understanding what is actually in a cannabis or hemp extract.

A good certificate of analysis can help show:

  • which cannabinoids are present;
  • how many milligrams or percentages are present;
  • whether THC is detectable;
  • whether the product matches its label;
  • whether contaminants have been tested for;
  • whether the batch is consistent.

This matters because words like hemp oil, hemp extract, CBD oil and full spectrum can be used loosely. Testing gives the label meaning.

Extract vs ingredient

This is another useful distinction.

Hemp seed oil is an ingredient pressed from hemp seeds. It is commonly used in food and skincare.

Hemp extract usually means compounds have been extracted from hemp or cannabis plant material. Depending on the plant part and extraction method, this may include cannabinoids such as CBD or THC.

A product can use hemp seed oil as a carrier oil while also containing CBD extract. That is why the ingredient list and cannabinoid panel both matter.

Why labels can be confusing

The phrase “hemp oil” is not specific enough on its own.

It might mean hemp seed oil. It might mean CBD oil. It might mean hemp extract. It might be used loosely to describe cannabis oil or medicinal cannabis oil.

This is why we prefer clear language. If we mean hemp seed oil, we say hemp seed oil. If a product contains CBD, that should be identified clearly and regulated appropriately.

Clear language helps customers understand what they are looking at, and it helps protect trust in the hemp and cannabis industry.
