Herbs to help improve memory and focus

Looming exams or work deadlines can really run riot with our nervous system and ramp up our stress levels. When you then add into the mix the thought of having to memorise or regurgitate reams of information, the stress can become unmanageable.

It’s always tempting to burn the midnight oil and reach for the classic stimulants such as coffee, sugar and chocolate. While they might provide some short-term stress relief, the long-term effects can be somewhat harmful and make us feel more exhausted and stressed. Thankfully, there are some top herbal heroes and Ayurvedic medicines for brainpower that you can try that will not only target the stress but also improve overall concentration and cognition. Here are our top five brain-boosting herbs that emerge as the ultimate answer to how to improve memory power naturally:


The mind enhancing, and nervous system soothing effects of this plant are legendary, especially when you aspire to train your brain on how to focus better. Brahman is the Hindu name given to the universal consciousness and Brahma is the divinity responsible for all ‘creative’ forces in the world. Brahmi literally means the ‘energy’ or ‘shakti’ of Brahman. With brahmi deriving its name from these roots it has a lot to live up to, and it does in terms of improving memory and focus. Brahmi is documented in ancient Indian texts as far back as the 6th century and is widely used as a natural remedy for people struggling with how they can improve brain function.

This herb improves circulation to the brain, positively impacting upon cognitive functions such as memory through improving movement between nerve cells in the brain. Brahmi is also balancing the response of stress hormones, thereby acting as a natural stress relief.

Brahmi is the excellent long-term choice for boosting overall brain performance and increasing your capacity to learn and memorise.

Gotu Kola 

Gotu kola has been used in Asia for thousands of years, both as a medicine and as a food. One of the earliest Ayurvedic medical texts compiled around 300 C.E, ‘Sushruta Samhita’, describes this herb as being able to improve mindfulness, act as a form of stress and anxiety relief, revitalise consciousness and maintain youthful wit!

Gotu kola improves circulation to the brain, supporting cognitive functioning such as memory and concentration whilst also protecting the brain tissue from damage caused by free radicals. The memory plant has distinctive round leaves, often described as ‘brain-shaped’, which interestingly conforms with the ‘doctrine of signatures’ – an ancient belief that herbs resemble parts of the body that they are used to treat, making Gota kola a potent ingredient of Ayurvedic medicines for brain power.

Gotu Kola is very similar in some ways to brahmi, in terms of its physiological effects on the brain. But, interestingly, gotu kola also has an effect on skin quality and so is excellent for people who experience skin break-outs as a result of stress. So, if you notice you accumulate a couple of extra spots, or your eczema flares up around exam time and want to know how to improve memory – this herb could be the perfect solution.


Tulsi, also known as ‘holy basil’ is a very special memory plant. It’s believed to awaken the mind bringing mental clarity whilst also relaxing the nervous system, allowing time for the restoration of adrenal glands that may have become exhausted by stress or anxiety.

It modulates the stress response by acting as a natural stress relief, increases adaptive energy and nourishes the vital spirit. It is the perfect antidote to the pressures of modern life. It has adaptogenic qualities and improves the systemic response to physical, biological, emotional and environmental stress enabling one to enjoy more stamina and ultimately improve memory and concentration.

Tulsi is an excellent option for those of us who become very anxious about looming exams or challenges and often find themselves trapped with the question of how to concentrate better. Tulsi is perfect for the emotional distress that can be caused by exam stress. The added benefit is that tulsi will also improve the physiological functioning of the brain and still support the enhancement of memory and learning capacity. Tulsi can be taken short and long term for increasing memory power naturally. It tastes delicious as a tea, so why not try Pukka's Tulsi Clarity when you feel yourself becoming a little anxious about the day ahead, or as a night-cap to stop a racing mind at night.


Turmeric is a renowned super-spice. It targets almost every body system and works as an all-round anti-inflammatory and antioxidant. But why is this beneficial for the brain? Well, the powerful anti-inflammatory effects of turmeric, combined with its antioxidant capability mean that it is incredibly protective to the brain. It also boosts cardiovascular health and the circulation, including circulation to the brain. So turmeric, root thought to help with memory has the ability, like brahmi and gotu kola, to enhance overall cognitive functioning whilst also providing a high level of protection- a great herb for the developing brain of students who are in search of effective ways to improve memory and concentration.

Turmeric is an excellent all-rounder and tastes delicious both in food and in tea. It can also prove very beneficial for the digestion, so it might be a good option for those who find that their digestion becomes a bit unsettled in times of extreme stress. Also, if you enjoy exercise as a form of stress relief and a way to improve memory, turmeric is well-known for improving athletic capability, through increasing blood flow and oxygen to the muscles and joints.

Green tea and matcha

Both green tea and matcha are produced from the same plant, but matcha is more concentrated. Both are packed with antioxidants, which help protect the system from free radical damage while improving memory and focus. Green tea and matcha also contain various compounds that are associated with uplifting heart health in addition to stress relief and increasing alertness.

Green tea and matcha naturally contain caffeine as they are both made from the same plant that you get regular black tea from. However, the difference between green tea, matcha and coffee is that the green tea and matcha contain a compound known as L-theanine, which is an amino acid that works synergistically with other compounds present in the plant such as caffeine to increase serotonin, dopamine and gamma-aminobutyric acid (GABA) in the brain, all of which significantly boost mood and offer stress relief.

In addition to this, L-theanine, balances the effect of caffeine and helps prevent the characteristic ‘crash’ that you get associated with coffee, making it one of the most potent compounds for improving memory and concentration.

Green tea and matcha taste great and are the perfect alternative to coffee and energy drinks. Try and replace at least one with a cup of green matcha tea so that you not only get your energy boost but also relieve tension and support the brain to aid concentration.

Ways to use plant power to enhance your day:

  • If you have an oil burner at home, add a couple of drops of rosemary oil to boost brain power.

    Confused about how exactly is rosemary good for memory ? As Shakespeare once said ‘Rosemary, that’s for remembrance’. Rosemary improves circulation to the brain and has been shown to boost memory.

  • Keep an oxygenating plant nearby, or on your desk to help keep your environment fresh and healthy. Top oxygenating plants are aloe vera, ferns, bamboo and spider plants.

  • Cook with herbs. Common spices such as ginger, black pepper, chilli and turmeric all boost circulation and can be great if you are struggling with memory and concentration. Try and incorporate them into your daily cooking routine.

Stress levels and your dosha

In Ayurveda, there are three different health constitutions or ‘types’ known as dosha that can be used to help identify why people certain people are affected by specific health conditions and how we can treat them. The three dosha are vatakapha and pitta. Here is how each of the doshas is likely to be affected by stress and how you can help support them. Take our dosha quiz to find out which is your dominant dosha.


Vata types tend to be affected the most by anxiety and can become quite stressed by the thought of looming exams. They may also tend towards ‘panic’ studying and burn the candle at both ends out of a fear or concern over not passing the exams

For strong vata types, tulsi is the perfect herb as it helps tackle the emotional stress associated with exams.  Along with the stress relief properties of tulsi, vata types will also really benefit from a daily mindfulness practice, or a stress-balancing exercise such as yoga to help calm frazzled nerves.


Pitta types are typically hot and fiery in their emotions and are likely to either be pretty ‘gung-ho’ in their reaction to revision, due to their naturally competitive streak or, they may air on the slightly more care-free side, which demands better focus and memory.

Either way, they can become irritable, angry or hot-tempered when stressed. So, cooling and protective herbs for the brain such as brahmi and gotu kola will help boost their cognitive capacity whilst also keeping them cool and calm.

Pitta types keen on improving memory will really benefit from making sure they take some time out and about in nature, whether that be a gentle stroll or a sprint. It is one of the best ways to relieve stress as it clears excess heat and melt away any irritation or frustration.


Kapha types are normally pretty laid back and can have a relatively lazy approach to revision, avoiding the inevitable. However, kapha types can also be very determined and set themselves strict and well-organised revision timetables.

Either way, the issue with kapha types often centres on energy levels, as they tend to be quite low. So, herbs that help boost memory and concentration, as well as overall energy, can be very useful here such as green tea, matcha and turmeric.

Kapha types who are concerned about how to focus better can benefit from structure, so try making yourself a revision plan with timed breaks so that you can manage the thought of the day ahead without feeling overwhelmed. Also, time the revision to a time of day that works for you as this will offer the required stress relief. If you’re not a morning person then why not take a break in the mornings and work later into the evening to introduce harmony in your schedule and most importantly improve memory and brainpower effectively.
