The Best Cannabis Strains for Medicinal Purposes

Medicinal Cannabis Seeds Australia Best Strains for Medical Use

While there is no single type of cannabis strain described as a “Medical”, different cannabis seeds produce genetics with very different cannabinoid and terpene profiles, which is why CG Australia’s collection includes CBD-focused varieties alongside famous strains such as Cheese (The U.K based Medical strain), Northern Lights, Gorilla Glue (GG4), OG Kush, Girl Scout Cookies and White Widow.

When comparing medical cannabis seeds in Australia, consider more than THC percentage alone. A strain’s THC and CBD levels, Indica/Sativa balance, terpene profile and commonly reported characteristics can all help distinguish one variety from another.

What Makes a Cannabis Strain "Medicinal"?

The term medical cannabis strain is often used fairly broadly. A high THC percentage alone does not make a strain medicinal, and neither does being Indica dominant.

Cannabis genetics can produce very different concentrations and ratios of cannabinoids, including THC and CBD, alongside aromatic compounds known as terpenes. This means strains associated with medicinal cannabis can range from low-THC, CBD-rich genetics through to balanced hybrids and potent THC-dominant varieties.

For collectors comparing medicinal cannabis seeds, cannabinoid profile therefore provides a more useful starting point than simply looking for the highest THC percentage.

CBD-Rich Cannabis Strains

THC vs CBD in cannabis strains what is the difference guide

CBD-rich genetics are particularly important when discussing medicinal cannabis because they provide a substantially different cannabinoid profile from conventional high-THC strains.

CG’s CBD Nepal Gold and CBD White Widow have been specifically selected for elevated CBD characteristics and provide alternatives for collectors interested in cannabis genetics bred around cannabinoid balance rather than maximum THC potency.

CBD, or cannabidiol, does not produce the conventional intoxicating effects associated with THC and has become an important focus of modern cannabis breeding and cannabinoid research.

THC and CBD are the two best-known cannabinoids found in cannabis, but their characteristics are very different.

THC (tetrahydrocannabinol) is responsible for most of the intoxicating effects normally associated with cannabis. Two THC-dominant strains can nevertheless have noticeably different characteristics because genetics, cannabinoid ratios and terpene profiles all contribute to the overall strain.

CBD (cannabidiol) does not produce the same conventional intoxicating high as THC. CBD-rich genetics have consequently become an important area of cannabis breeding and scientific research.

Modern medicinal cannabis is not restricted to either one. Cannabinoid profiles can range from strongly CBD dominant through more balanced CBD/THC profiles to strongly THC-dominant products.

This is why CG’s medical cannabis seed collection deliberately includes both CBD-focused genetics such as CBD Nepal Gold and CBD White Widow and THC-dominant varieties such as Gorilla Glue and Girl Scout Cookies.

Indica-Dominant Medical Strains

Indica-dominant genetics are among the varieties most frequently associated with evening relaxation and heavier physical effects.

Classic examples include Northern Lights and OG Kush, while modern hybrids such as Girl Scout Cookies and Gorilla Glue combine substantial Indica influence with high resin and cannabinoid production.

Northern Lights in particular has remained one of the world’s most recognised Indica strains for decades. Its Afghani-derived genetics, approximately 90% Indica dominance, relatively fast flowering and famously relaxing characteristics have helped it remain popular despite thousands of newer hybrids entering the market.

High-THC Cannabis Strains

Some collectors researching medical cannabis seeds are particularly interested in THC-dominant genetics.

Strains such as Gorilla Glue, Girl Scout Cookies and Bruce Banner #5 can produce substantially higher THC levels than CBD-rich cultivars.

However, stronger does not automatically mean better. THC potency varies considerably between strains and individual plants, while the overall characteristics of a cultivar are influenced by its wider cannabinoid and terpene profile.

THC percentage is therefore best considered alongside cannabinoid balance, genetics, terpene profile and the broader characteristics of the strain.

 

Most Popular Medical Cannabis Strains

1. Cheese

 

The legendary UK Cheese phenotype is another established Indica-dominant cultivar that has long been associated with medicinal cannabis users.

Its approximately 60% Indica / 40% Sativa profile produces a combination of uplifting initial characteristics followed by increasingly pronounced physical relaxation.

Cheese is also famous for one of the most distinctive terpene profiles in cannabis, producing its unmistakably pungent, savoury and skunky aroma.

THC Levels (max up to)
12 %
  • Genetics: Skunk#1 / UK Cheese lineage
  • Strain Type: Hybrid
  • Dominance: ~60% Indica / 40% Indica
  • THC: Typically 18-21%
  • CBD Content: Minimal, usually below 1%
  • Yield (Indoor): Up to 550 g/m² under favourable conditions
  • Yield (Outdoor): Medium/High (Highly environmental-dependant)
  • Height: Medium to tall with strong branching
  • Flowering Period: Around 8-9 weeks
  • Flavour Profile: Earthy, musky, pungant, sharp
  • Growing Difficulty: Easy to intermediate
  • Best Suited to: Indoor, greenhouse or outdoor with low humidity

2. Northern Lights

Northern Lights is one of the most famous Indica strains ever developed and an obvious inclusion in a collection of medicinal-style cannabis genetics.

CG’s Northern Lights is approximately 90% Indica / 10% Sativa, with THC generally around 16–24% depending on phenotype and growing conditions.

Its reputation centres on pronounced physical relaxation and a calm, dreamy character. These characteristics have helped make Northern Lights particularly well known among people researching relaxing and nighttime cannabis strains.

We also supply Auto Northern Lights for faster growing cycle.

THC Levels (max up to)
12 %
  • Genetics: Northern Lights lineage – predominantly Afghani indica genetics
  • Strain Type: Hybrid
  • Dominance: ~90% Indica / 10% Indica
  • THC: Typically 16-21%
  • CBD Content: Minimal, usually below 1%
  • Yield (Indoor): Up to 550 g/m² under favourable conditions
  • Yield (Outdoor): Medium/High (Highly environmental-dependant)
  • Height: Medium to tall with strong branching
  • Flowering Period: Around 7-8 weeks
  • Flavour Profile: Earthy and woody with pine, spice and occasional citrus/fruit notes
  • Growing Difficulty: Easy to intermediate
  • Best Suited to: Indoor, greenhouse or outdoor with low humidity

Other Common Medical Cannabis Strains

Gorilla Glue (GG4)

Gorilla Glue #4, usually shortened to GG4, combines Sour Dubb, Chem’s Sister and Chocolate Diesel genetics and has become one of the defining high-potency hybrids of modern cannabis breeding.

It can reach very high THC levels and is renowned for combining powerful cerebral effects with pronounced physical relaxation.

GG4 is frequently discussed within the medicinal cannabis community in connection with its potent and relaxing characteristics. It also provides an important contrast to CBD-rich genetics because it represents the high-THC end of the cannabis spectrum.

OG Kush

Another cornerstone of modern cannabis breeding, OG Kush combines high THC with strong Indica characteristics.

CG’s OG Kush is approximately 75% Indica / 25% Sativa and generally produces around 18–23% THC.

It has a classic earthy, pine and citrus terpene profile and is particularly well known for combining cerebral euphoria with substantial physical relaxation.

OG Kush is also important genetically. Its influence can be found throughout numerous modern American cannabis varieties, including descendants such as Girl Scout Cookies.

Girl Scout Cookies

Girl Scout Cookies (GSC) combines OG Kush with Durban-derived genetics to produce a highly potent modern hybrid.

With THC commonly around 22–28%, GSC can provide substantially greater potency than many traditional cannabis varieties while retaining a strong Indica influence.

Its distinctive combination of cerebral elevation and deeper physical relaxation is one reason the strain has become enormously influential in both recreational and medicinal cannabis breeding.

CBD Nepal Gold

At the opposite end of the cannabinoid spectrum is CBD Nepal Gold.

Rather than concentrating on maximum THC, this strain has been selected for a comparatively CBD-rich cannabinoid profile.

That makes CBD Nepal Gold particularly interesting for collectors researching the differences between conventional THC-dominant cannabis seeds and genetics bred specifically around increased cannabidiol content.

CBD White Widow

CBD White Widow takes the famous White Widow genetic background in a more CBD-focused direction.

It provides another option for collectors interested in CBD cannabis seeds rather than simply selecting the most potent THC-dominant strain available.

Together, CBD White Widow and CBD Nepal Gold help make CG’s medical-strain collection genuinely diverse rather than simply another category containing high-THC Indica seeds.

White Widow

First made famous in the Netherlands during the 1990s, White Widow remains one of the world’s best-known balanced cannabis hybrids.

Its Brazilian Sativa and South Indian Indica heritage produces a combination of cerebral and physical characteristics rather than an overwhelmingly sedating effect.

For those comparing different medicinal-style cannabis genetics, White Widow occupies an interesting middle ground between heavily relaxing Indicas and more energetic Sativa-dominant cultivars.

Bruce Banner #5

Not every strain associated with medicinal cannabis is strongly Indica dominant.

Bruce Banner #5 provides an excellent contrast. This potent OG Kush × Strawberry Diesel hybrid is Sativa leaning and can reach THC levels approaching the high-20% range under favourable conditions.

Its character tends to be considerably more uplifting and cerebral than Northern Lights or OG Kush, demonstrating why medical cannabis strains cannot sensibly be grouped into a single Indica-based category.

Indica or Sativa for Medicinal Cannabis?

The familiar Indica-versus-Sativa distinction can be useful when comparing how cannabis plants grow and broadly describing traditional strain characteristics, but it should not be treated as a medical classification.

Indica-dominant cultivars such as Northern Lights and OG Kush are generally associated with heavier physical relaxation and are consequently often discussed in connection with evening or nighttime use.

Sativa-leaning genetics such as Bruce Banner #5 tend to have a more uplifting and cerebral reputation.

Balanced hybrids such as White Widow and Gorilla Glue occupy territory between these two traditional classifications.

When comparing medicinal cannabis seeds, it is therefore better to consider the complete genetic and cannabinoid profile rather than relying solely on an Indica/Sativa percentage.

Medical Cannabis Seeds - FAQ

There is no single best medical cannabis strain because different cultivars have substantially different cannabinoid, terpene and genetic profiles. Popular genetics frequently associated with medicinal cannabis include Northern Lights, OG Kush, Gorilla Glue, White Widow and Girl Scout Cookies, while CBD-rich varieties such as CBD Nepal Gold and CBD White Widow provide a very different cannabinoid profile.

Medical cannabis seeds generally refers to cannabis genetics associated with cannabinoid or strain characteristics of interest within medicinal cannabis. They are not a separate botanical type of seed. Depending on the strain, the genetics may be CBD-rich, balanced, THC dominant, Indica dominant or hybrid.

Indica-dominant strains are often associated with pronounced physical relaxation and evening use, which contributes to their popularity among medicinal cannabis consumers. However, Sativa-dominant and balanced strains are also associated with medicinal use. Cannabinoid and terpene profiles provide more information than the Indica/Sativa label alone.

Perhaps, but not necessarily. High-THC varieties produce stronger intoxicating effects, but greater potency does not automatically make a strain more appropriate for medicinal purposes. CBD-dominant, balanced and THC-dominant cannabinoid profiles are all found within medicinal cannabis.

Gorilla Glue, Girl Scout Cookies, Bruce Banner #5, OG Kush and Northern Lights are examples of well-known THC-dominant genetics frequently associated with medicinal cannabis.

CBD-rich strains have been selectively bred to produce increased concentrations of cannabidiol relative to conventional THC-focused genetics. CG’s CBD Nepal Gold and CBD White Widow are examples of cannabis seeds selected with increased CBD characteristics in mind.

Northern Lights has a long history of popularity among medicinal cannabis consumers. Its strong Indica genetics and characteristically relaxing profile are among the reasons it is frequently associated with nighttime cannabis use.

There is not necessarily a genetic boundary between the two. The same cannabis cultivar may be associated with both recreational and medicinal use. “Medical strain” generally describes genetics of interest because of their cannabinoid profile, terpene profile or commonly reported characteristics rather than a completely separate type of cannabis plant.

Australian cannabis laws are complex and can differ between federal, state and territory jurisdictions. Medicinal cannabis itself is regulated and legal access generally occurs through an authorised healthcare practitioner and the applicable Australian medicinal-cannabis pathways. Customers should check the laws applicable to their location before purchasing, possessing, germinating or cultivating cannabis seeds.
