For thousand of years plants have been used to activate the natural cannabinoid responses of the body and nervous system by native and indigenous healers. In all cases these so called “master plants” have been taken in a full or whole plant form. The more recent Western approach with master plants like cannabis sativa have focused on isolating and consuming pure extracts of single components – for example CBD (cannabidiol) isolate1. So the question begs, is there any benefit to taking a full-spectrum array from a cannabinoid regulator or is it best to use a standardised single component isolate? New research has pointed in the direction of full-plant forms of cannabinoid regulators as these have demonstrated an “entourage effect”2 in which a variety of “inactive” metabolites and closely related molecules markedly increased the activity of the primary endogenous cannabinoids in our bodies – anandamide (AEA) and 2-arachidonoylglycerol (2-AG). Below we discuss what we now know about the endocannabinoid system and important information in using it therapeutically. We also evidence the entourage effect and discuss the pros and cons of different cannabinoid activators

New studies are showing that synergy occurs between molecules with full-plant forms or extracts compared to isolating out single compounds. This entourage approach is now more commonly accepted as the ideal way to regulate our own endocannabinoids.2

The Endocannabinoid System (ECS)

The endocannabinoid system (ECS) is a security and defense system that seeks to maintain internal harmony and balance within the body. It is linked with and can regulate the nervous, immune, hormonal or the endocrine systems3 and the enteric nervous system (ENS)4 of the gut sometimes called the “second brain”. The ECS acts like a master switch to control all other systems

The role of the ECS is to relay important and timely information between these systems, but also prepare the body to adapt to external or internal stressors3. Acting as an inbuilt thermostat the ECS seeks out and maintains the homeostatic balance point for each of the body’s systems and responses to the external environment. Think of it like a thermostat on a heater set to maintaining the room at a desired temperature that is comfortable for all.

The ECS responds to various stimuli, like injury, chronic inflammation, different forms of pain and infections3. It protects cells and cell components, like the mitochondria and nerve cells, which are highly sensitive and prone to damage. In addition, the ECS attempts to re-balance and remove other toxic insults, like carcinogens, solvents, UV light, pesticides, and more3.

The ECS can be activated to help treat and manage the following health conditions5:

  • Fibromyalgia

  • Osteoarthritis

  • Polymyalgia rheumatica

  • Low back pain

  • Neuropathic pain

  • Endometriosis

  • Inflammatory or irritable bowel pain

  • Migraine, etc.

  • Chronic Fatigue/ME

  • Anxiety

  • Depression

  • PTSD

  • Insomnia

  • ADHD

  • Premenstrual Syndrome (PMS)

  • Chronic pain

  • Tourettes

  • Autism Spectral Disorders (ASD)

Cancers including:

  • Breast

  • Bowel

  • Prostate

  • Lung

  • Cervical

  • Brain including: Glioblastoma multiforme (GBM)

  • Melanoma

  • Seizures

  • Autism spectrum with challenging behaviour

  • Parkinsons Disease

  • Peripheral Neuropathy

  • Muscle Spasms

  • Multiple Sclerosis

  • Essential Tremor

  • Brain trauma/damage

Anandamide and the ECS – How it Works

The ECS is all throughout the body and consists of signalling molecules called endocannabinoids (ECBs – keys) and receptors (locks). The main cannabinoid receptors are called CB1 and CB2,  while the signalling molecules that unlock them are called anandamide (AEA), and 2-acyl glycerol (2-AG), collectively known as ECBs. Research has also discovered other receptors linked to the ECS including GPR55, GPR119, the ion channel receptor TRPV1 through which pain is mediated and PPAR-alpha receptors, located in the nucleus of cells, that take part in regulating genes associated with pain and inflammation.

When harmful triggers like inflammation and injury act on the body, the ECS activates production of ECBs like AEA or 2-AG from the membranes of cells in the vicinity of the injury. ECBs are produced on demand whenever the body requires their services. AEA for example can respond to external stimuli by activating the CB1 receptor in the brain and influence production of serotonin and regulation of the HPA response of the body – our body’s main stress response system.6 Through this approach the nervous system can rapidly adapt the body’s physiological response to the original stimuli and return balance and harmony (Figure 1).

Figure 1. Anandamide regulates the nervous system by feeding back messages to the CB1 receptor allowing adaption to external or internal stimuli.

How to activate the ECS

1. Directly

By using exogenous molecules not produced by the body that directly bind the CB1 or CB2 receptors known as exocannabinoids or cannabinomimetics. The most well known of these is the plant cannabinoid Tetrahydrocannabinol (THC) present in some strains of cannabis. Beyond this there are many other plants and cannabinomimetics that have been discovered to directly bind the cannabinoid receptors, for example Salvinorin A from the plant Salvia Divinorum, Yangonin from Kava Kava and Perrottetinene from New Zealand Liverwort (Figure 2). All four of these examples are molecules extracted from traditional medicines used by different cultures to treat and manage pain or for enhancing spiritual practices.

The benefits of using a direct cannabinomimetic is that it acts rapidly with high potency. It can offer relief for severe or chronic conditions associated with pain and can assist in the treatment of chronic inflammation. The drawbacks are that it can be difficult to dose adjust to ensure that desensitisation of CB receptors do not occur. Using cannabinomimetics like THC regularly or excessively increases risk for developing dependency on it and can result in an inability to manufacture sufficient natural ECBs like anandamide. People who develop dependency on cannabinomimetics may find they suffer from withdrawal effects like brain fog, lethargy and anxiety when the mimetic is withdrawn. In addition, some CB1 agonists like THC can be psychoactive, a property that is not ideal for everyone and often not wanted when consuming it for medicinal benefits.

2. Indirectly – the entourage effect

By using molecules not produced by the body that increase production or sensitivity of our natural endocannabinoids like Anandamide, but do not themselves bind the CB1 or CB2 receptors. This is known as the cannabinoid entourage effect. Studies in cannabis have shown that using pure THC or CBD (isolate) is not as effective as the whole plant extract as different components in the full plant work in synergy to promote enhanced healing over any one single compound. The entourage effect may occur through different mechanisms, e.g., preventing the breakdown of the ECB’s by enzymes that are responsible for their destruction in which case the ECB’s last longer in the body giving a prolonged and enhanced action, or improving the binding of ECB’s on various receptors, or by activating other receptors, e.g., opening up ion channels that causes a synergistic effect of the major molecule. The most commonly targeted ways to improve cannabinoid entourage are via inhibition of FAAH – the key enzyme that breaks down our ECB’s or through slowing re-uptake of ECB’s. Plants like Peruvian maca act as entourage enhancers through a series of FAAH inhibitors known as macamides that are produced during the traditional drying and preparation processes. In addition, quality ceremonial cacao paste can contain N-acetyl-ethanolamines that also can act as FAAH inhibitors to enhance the natural production and function of ECBs. Both maca and cacao have been traditionally used for their abilities to indirectly regulate the ECS and improve resilience to stress (Figure 3). A further class of entourage enhancers called terpenes is discussed in more detail below.

Endocannabinoids have significant advantages over exocannabinoids or cannabinomimetics. They are locally produced, so act at the site of production and are more specific. The amount the body produces is in proportion to the demand, and the dose is well known. Once they have performed their service they are quickly broken down by the body and recycled back to the components of cellular membranes from which they originated. As a result there is little to no issues with side-effects or dependency and different entourage plants or extracts can be combined for more enhanced synergy. They can be used long-term and are well tolerated.

How to create entourage using maca and cacao

Maca is a traditional medicine used in Peru to improve health and well-being and to bring balance and build resilience towards stress. When correctly prepared maca produces molecules called macamides that act as FAAH inhibitors. Inhibition of FAAH can increase the production and lifespan of our natural cannabinoids like anandamide as well as improving sensitivity of cannabinoid receptors. Not all maca is equal however and it is important to ensure that you are using a traditionally prepared quality maca powder that has been tested and standardised for macamide levels. The right type of maca to use depends on the condition being treated.

Certain cacao beans and ceremonial cacao paste can contain molecules called N-acetyl-ethanolamines that also can act as FAAH inhibitors. As these molecules are fat soluble it is important to find a quality cacao paste or full cacao beans/nibs as these are the highest sources of N-acetyl-ethanolamines. Cacao powder does not contain the same levels as its full bean equivalents.

Daily consumption of maca and cacao provides FAAH inhibitors that increase and protect natural anandamide from rapid breakdown, allowing better regulation of the ECS (Figure 4). This entourage enhancement of activity can improve health outcomes for those struggling with issues like hormonal imbalances, chronic inflammation, mental health, adrenal or endocrine imbalances, cancer and more. It can also combine with and alleviate some of the negative side-effects of using direct cannabinomimetics.

This can improve our total body health and well-being, especially when dealing with chronic health conditions (right).

Mood elevation and entourage with terpenes

Terpenes are a large and diverse class of organic compounds produced by a variety of plants. Terpenes are what give each flower, herb, and fruit its unique scent and flavour. Every day, everywhere you go, you encounter terpenes. When you zest a lemon, you smell terpenes. Open a jar full of herbs; what you sense is the terpenes. Stop and smell the roses? More like stop and smell the terpenes. Terpenes are aromatic compounds that, when inhaled, applied to the skin or consumed, enhance our sensory experience and greatly influence flavours and aromas (Figure 5).

The cannabis plant is known to contain more than 100 terpenes,7 and most plants contain only a handful of terpenes, the different terpenes in cannabis are dependent upon a variety of factors such as the strain of cannabis, growing methods i.e., indoor/outdoor or environmental factors.8 Terpenes have been shown to work in synergy with both exogenous and endogenous cannabinoids to promote the entourage effect’.9

Research10 indicates that combining specific terpenes (Limonene, Pinene, Myrcene, Linalool, etc.) with cannabinoids can improve efficacy in treating mood disorders, depression and anxiety. When it comes to cannabis all the constituents combine to create the experience. Thinking of this example like flying in an aeroplane as an analogy the cannabinoids such as THC, CBD control the altitude and velocity, but the terpenes provide the direction like the rudder. This direction, controlled by the terpenes, is the feeling of being couch-locked, in a chill or calm state, or a focused and alert state.

Summary

  • The endocannabinoid system (ECS) is a vital part of our natural defence against illness and can promote better health and wellbeing. It can be used to treat a range of different health conditions.

  • It can be activated either directly or indirectly using cannabinoid plants, extracts or molecules via a range of different methods each with their own pros and cons.

  • Direct cannabinomimetics act fast, with high potency but require careful dose adjustment and monitoring to prevent system de-sensitisation.

  • Indirect cannabinoid regulators work to enhance the activity of our natural cannabinoids through different approaches including protection of endocannabinoid uptake, breakdown or increased receptor sensitising. This is known as the “entourage effect”.

  • Some common entourage molecules include macamides (from maca), N-acetylethanolamines (from cacao) and terpenes (from cannabis and other plants).

  • Entourage plants can be used to enhance a cannabis experience and to negate some of the negative side-effects associated with using direct cannabinomimetics.

  • It is important to select a quality form of an entourage plant as not all are created equal.
