If you have been curious about MCB Oil as a legal, plant-based alternative to traditional cannabinoid oils, you are not alone. Seleno Health’s M-CB Oil® (Maca-cannabinoid Oil) is positioned as the world’s only pure M-CB oil on the market, created entirely from legal plant extracts and now available in a sweet peppermint flavour, with a patent filed. It is a fresh take on daily balance, combining concentrated Andean Maca with a targeted approach to endocannabinoid system support.
At Greensmith Grocers, we are always looking for innovations that align with organic sourcing, real-world usability, and the kind of gentle, consistent support many people want for modern life.
What is MCB Oil, exactly?
M-CB Oil® is a maca-derived oil made from high-quality Andean Maca, the same traditional botanical used in many wellness routines, but extracted at a much higher concentration. Seleno Health describes this as 100x concentrated compared to standard maca preparations, designed for people who want the benefits of maca in a more potent, convenient format.
What makes it different from typical plant oils is the focus on “indirect cannabinoids” and their relationship with the endocannabinoid system (ECS). The ECS is a body-wide signalling network involved in maintaining balance, often discussed in relation to stress response, sleep, mood regulation, recovery and immune function.
Why the ECS matters for everyday wellbeing
You do not need to be an expert in receptors to understand the appeal here. Many people are looking for support that feels broad and foundational, not like a short-term stimulant or sedative. The ECS is often described as a “balancing” system, helping the body respond to changing demands such as busy schedules, intense training, disrupted sleep, or ongoing stress.
Seleno Health’s positioning centres on CB2 affinity and an entourage-style effect across multiple concentrated compounds. In plain terms, the idea is that a blend of naturally occurring plant constituents may work better together than a single isolated compound for some people.
The concentrated maca difference
Maca has a long history of traditional use, particularly for vitality, stamina and resilience. With MCB Oil, the focus is on a concentrated extract that aims to capture a wide spread of plant compounds in a small, easy-to-take dose. That “more in less” approach is one reason sublingual oils have become popular in wellness routines.
If you are browsing options and want something that fits neatly into a morning or evening ritual, you can start by exploring what’s available here:
Sublingual use: why it is popular
One of the standout features of MCB Oil is the recommended sublingual method, meaning you place the drops under the tongue, hold for around 60 seconds, then swallow.
Why do people like this approach?
- Faster uptake: Sublingual use may allow quicker absorption than swallowing straight away, because it can bypass some digestive processing.
- Easy titration: Drops make it simpler to adjust your routine gradually.
- Convenient: No capsules to swallow, and no need to prep anything.
The new sweet peppermint flavour is also a practical upgrade. If you have tried herbal oils before, you will know taste can be the difference between “occasionally” and “consistently”.
What people commonly use MCB Oil to support
While everyone’s experience is different, MCB Oil is commonly used in routines designed to support:
- Everyday aches and post-exercise recovery
- Healthy inflammatory response
- Immune system resilience
- Stress management and nervous system balance
- Sleep quality and wind-down routines
- Mood stability and mental wellbeing
- Focus and steady energy through the day
It is important to keep expectations realistic. Supplements are not a substitute for medical care, and results can vary depending on your baseline health, sleep, diet, stress load and consistency.
Terpenes and the entourage concept
Seleno Health notes the inclusion of entourage-enhancing terpenes. Terpenes are aromatic compounds found in many plants and are often discussed for their synergistic role in botanical formulas. The “entourage effect” is a popular term used to describe how multiple plant compounds may influence overall effects when taken together.
If you are sensitive to strong formulas, it is still wise to start low and build slowly. More is not always better, especially when you are learning how your body responds.
How to use MCB Oil
A simple routine matters, because consistency is usually what delivers the best value.
- Shake the bottle before use.
- Using a mirror if helpful, place the desired drops under your tongue.
- Close your mouth and hold for 60 seconds.
- Swallow, or follow with a drink if you prefer (herbal tea, plant-based milk, smoothie, or water).
Many people like using it:
- In the morning for steadier focus and energy support
- In the afternoon during high-stress periods
- In the evening as part of a wind-down routine

Dosage: start low, go slow
For beginners, Seleno Health suggests starting with 2 to 3 drops, 2 to 3 times per day for the first five days, then increasing gradually by 1 to 2 drops every five days until you find your comfortable level. Many people land in the range of 8 to 15 drops per day.
If you are pregnant, breastfeeding, taking prescription medications, or managing a diagnosed health condition, it is best to speak with a qualified health professional for personalised guidance.
What about drug testing and drowsiness?
MCB Oil is marketed as non-psychoactive and intended for everyday use, including when you need to stay alert. For anyone concerned about workplace screening, it is promoted as not containing the compounds typically targeted in standard THC drug tests. However, testing protocols vary between organisations, so if drug testing is critical for your work, it is worth confirming with your employer and a healthcare professional.
Conclusion: a modern, peppermint-flavoured approach to balance
With its patent-filed positioning, sweet peppermint flavour, and a concentrated maca-derived formula designed to interact with ECS pathways, MCB Oil sits at the intersection of traditional botanicals and modern wellness goals. If you are seeking a legal, plant-based oil that may support stress resilience, sleep quality, mood and recovery, it could be a thoughtful addition to a consistent routine, alongside good nutrition, movement and rest.
