Understanding the Nervous System and Nervines




Stress - we all know it and all experience it, but how do we become more resilient to it? This stress phenomenon is defined by the W.H.O as:

“any type of change that causes physical, emotional or psychological strain. Stress is your body's response to anything that requires attention or action. Everyone experiences stress to some degree. The way you respond to stress, however, make a big difference to your overall well-being.”

Further stating that it can manifest as:

“as fear, worry, inability to relax, increased heart rate, difficulty in breathing, Disturbance in sleeping patterns, change in eating patterns, difficulty in concentrating worsening of pre-existing health conditions (physical and mental) and increased use of alcohol, tobacco and other drugs.”


In 2018 the Mental health foundation in the UK conducted one of the largest stress related studies with 4619 respondents – of these 74% of people reported that they felt so stressed that they experienced overwhelm and the sense of not being able to cope. (R)

Further, in 2020 the APA declared a national mental health crisis when it came to stress levels due to the COVID-19 pandemic and the pressures that they placed on us as a collective. (R)

. . .


Long of the short is that more than ever we now have the beautiful opportunity to identify the stress we face in our lives, discern which stressors are ‘worthwhile’, implement life changes and shifts in coping mechanisms and strategies for dealing with stressors and overall supporting our minds, bodies and spirits in order to be able to navigate through them. This can take place in many forms – be it in receiving professional council, incorporating daily practices and rituals or finding herbal remedies to strengthen and restore your wellbeing.

The Nervous System holds a story - one which illuminates a means of understanding a physical mechanism of becoming more resilient and kind to our physical selves in order to nourish ourselves enough to ward off stress and live in a better state of alignment, health and wellbeing: 

 First off what is the nervous system and how does it work?

nervous system

 The nervous system is considered the most complex and deeply organised systems within the body – in action it receives information from sensory organs through nerves, this information is them transmitted through the spinal cord where it is processed in the brain – it is, in it’s glory, the blueprint off of which our body and mind are able to react to the world we live in.

In fact your body has billions upon billions of these nerve cells, 86 billion located in the brain alone! It manages everything from movement, thought and memory to blushing, blinking and the very much taken for granted act of breathing. The nervous system affects all areas of our lives, including the senses, movement, cognition, feelings, sleep, healing, the ageing process, heartbeat, breath patterns, stress response, digestion and affects other systems within or body’s too such as the adrenals, endocrine and enteric nervous system.


The nervous system makes use of incredibly special neurons which send messages all along the body – these messages allow for all the sensations we experience; from the tingling in your fingers, to watching the rain, hearing a bird, tasting a cup of tea and everything in-between – the mission of these nerves is to carry information about the environment you are in and communicate that to the brain in order to create a response.

There are different forms of neurons, namely:

  • Motor neurons – which allow for muscular mobility
  • Sensory neurons – which take information from our different senses of smell, touch, taste, sight and hearing
  • Other forms are those which control automatic actions such as breathing, regulating heartbeat, digestion and other processes in the body.

The Nervous System contains two main parts, each of which consists of billions of neurons:

  1. Central Nervous System (CNS): made of the brain and spinal cord, the CNS sees that the brain makes use of nerves in order to send communications to the entire body, each nerve has an outer coating which is called myelin (READ MORE ABOUT LIONS MANE), this ensures that these cells are protected and are able to deliver the messages clearly.
  2. Peripheral Nervous System: this consists of nerves which branch out from the CNS and extend throughout the body allowing for information to be relayed between the brain and spinal cord to your limbs, fingers, organs and toes. This includes:
    1. Somatic Nervous system – voluntary movements 
    2. Autonomic Nervous system – automatic activates like breathing. This regulates the functions of our internal organs and keeps our bodies running irrespective of the situations are are in.

Within the autonomic nervous system there are another two branches:

  • The sympathetic nervous system (arousing, fight-or-flight)  - this system aids the body with the fuel, energy boost and stimulation needed when it comes in contact with a stressor or trigger. The body is able to register a form of danger and upon this the adrenal glands are activated and stimulate cortisol – the heart begins to race, pupils dilate, heart increases and muscles tense up in an attempt to prepare the body to fly, fight, freeze or any other action which will allow survival. Symptoms of being in fight-or-flight include being fatigued yet feeling braced, not sleeping well, digestive issues, high blood sugar levels, energy level drops and never feeling like you can calm down or relax.
  • The parasympathetic nervous system (calming, rest-digest-heal) – relaxation is the name of the game here, allowing for the all essential process of healing, restoration and digestion. This process kicks in during a calming downtime space, and in all actuality is where we should be living most of the time in our day to day lives - when not in an emergency or faced with danger. This state allows for healthy digestion, hormonal balance, calm breath, easeful heart rate and healing in which the body can relax, regulate, regenerate, detox and restore.


So then what is a nervine and how can it help?




Nervines are a class of plants which are able to have a beneficial effect on the nervous and limbic systems in terms of providing support.

They aid in allowing for the active state of the sympathetic to switch over to the parasympathetic system, allowing for the nervous system to re-establish healthy and balanced nerve function. When it comes to the nervous system, it is important to remember that in many ways it is our first line of defence when dealing with stress, and therefore should be incorporated when treating a range of maladies and imbalances throughout the body.

They are differentiated into 3 categories through their actions and how they are able to act within the nervous system:

Nervine tonics aid in strengthening and feeding the nervous system in order to restore and regenerate the tissues of the neurons themselves – these medicines are often also incredibly mineral dense, can be adaptogenic and aid in supporting the body in numerous ways.
