What is guayusa (Ilex guayusa)?

Ilex guayusa is an evergreen tree from the holly family (Aquifoliaceae), growing in the humid rainforests of the Amazon – mainly in Ecuador, Peru, and Colombia. Its leaves have been used for centuries to prepare an aromatic, stimulating infusion. Modern science increasingly examines guayusa, and studies on its composition and guayusa properties confirm what Indigenous communities of South America have known for generations – that its leaves contain a harmonious blend of nature and energy.

Dried leaves contain, among others, caffeine, theobromine, polyphenols (such as chlorogenic acid and flavonoids) and amino acids, including L‑theanine. Together they contribute to gentle stimulation, support concentration, and create a sense of mental clarity. Unlike coffee, guayusa’s effect is more stable – energy appears gradually and lasts longer. This balance between stimulation and calmness is what makes guayusa increasingly popular among people seeking conscious, natural sources of energy.

Guayusa – what is it?

Simply put, guayusa is an infusion prepared from the leaves of the Ilex guayusa tree. It resembles tea in appearance, but in terms of effect it is closer to coffee or yerba mate – thanks to its natural caffeine content. Its flavour, however, is noticeably milder. Instead of bitterness and astringency, it offers a lightly sweet, herbal profile with subtle earthy notes.

The bioactive compounds in Ilex guayusa work synergistically: caffeine and theobromine support alertness and focus, while natural antioxidants (including flavonoids and phenolic acids) help counteract the impact of free radicals. Thanks to this composition, guayusa tea is often described as a source of “clean, clear energy” – not overly intense, but pleasantly noticeable.

Origins and tradition of drinking guayusa in South America

Guayusa has a long history reaching back to pre‑Columbian times. Ethnobotanical studies show that it was cultivated and used by communities in Ecuador, Peru, and Colombia – particularly among the Kichwa and Jívaro peoples. Infusions from Ilex guayusa leaves were drunk at dawn during communal gatherings around the fire. The ritual combined the physical with the spiritual – it was said to provide strength before hunting, heighten alertness, and reinforce bonds within the community. Stories, songs, and reflections on the dreams of the previous night filled the morning air.

Today guayusa is no longer a secret of the Amazon. It is appreciated not only in South America, but also around the world as a natural source of steady energy that does not lead to the sudden crashes often associated with coffee. Modern pharmacological studies highlight that its unique combination of caffeine, theobromine, L‑theanine, and polyphenols is responsible for the gentle yet effective stimulation.

Guayusa vs. yerba mate – similarities and differences

At first glance, guayusa and yerba mate seem similar – both belong to the Ilex genus, come from South America, and contain natural caffeine. However, they differ significantly in flavour and effect. Guayusa has a mild, lightly sweet profile with no bitterness, and does not require traditional accessories like a gourd or bombilla, making it more universal in daily brewing. Yerba mate, on the other hand, is more intense, with a distinct, herbal bitterness that many enthusiasts consider its hallmark.

In terms of effect, both plants stimulate, but in different ways. Guayusa delivers energy gradually, creating long‑lasting alertness without tension. The presence of theobromine – also found in cacao – supports circulation and softens caffeine’s impact. This is why guayusa is often described as “the balance between the strength of yerba mate and the calmness of tea”.

Properties of guayusa tea

Although guayusa tea has only recently gained popularity outside South America, its potential has been appreciated for centuries. Indigenous people of the Amazon drank it to regain strength, maintain alertness, and clear their thoughts at dawn. Today, more and more people reach for an Ilex guayusa infusion not only in search of energy, but also as a way to bring daily balance – between stimulation and calm.

Regular consumption of guayusa may support concentration, mental performance, and overall wellbeing. The natural bioactive compounds it contains – caffeine, L-theanine, theobromine and antioxidants – work synergistically, providing a sense of mental clarity without the abrupt stimulation that coffee often causes. Thanks to this, guayusa tea acts as a subtle “booster” for body and mind – it energises while helping maintain internal peace and balance.

Composition of guayusa – caffeine, theobromine, antioxidants

The exceptional effect of Ilex guayusa infusion comes from its rich phytochemical profile. Research shows that dried leaves contain on average 1.7-3.2% caffeine, a similar amount to green tea or mild coffee. A cup of the infusion (approx. 250 ml) typically contains 60-90 mg of caffeine – sufficient to stimulate the mind without an unpleasant sudden spike of energy.

• ✔️ Caffeine – stimulates the nervous system, improving alertness and cognitive performance. In guayusa, its effect is gentler than in coffee because it is balanced by other compounds.
• ✔️ L-theanine – an amino acid also found in tea, and present in meaningful amounts in guayusa. It supports relaxation and concentration, softens the impact of caffeine, and helps maintain calm mental focus. It is largely responsible for the harmonious stimulation characteristic of guayusa.
• ✔️ Theobromine – a natural compound also found in cacao; it supports circulation, has a mild vasodilating effect, and contributes to sustained energy.
• ✔️ Polyphenols – including chlorogenic acid and flavonoids such as rutin, quercetin, and kaempferol. These antioxidants help neutralise free radicals and support natural cellular defence processes.
• ✔️ Triterpenoids – such as ursolic and oleanolic acids – researched for their potential influence on metabolism and their ability to protect cells against oxidative stress.

It is the synergy of caffeine, L-theanine, and theobromine that makes guayusa tea such a balanced source of stimulation. The energy builds gradually, lasts longer, and does not end with a sudden drop. Antioxidants further support cellular protection and the body's vitality.

Effects of Ilex guayusa on the body

Guayusa tea has a broad impact – on the nervous system, circulation, and metabolism. The caffeine it contains works in harmony with theobromine and amino acids, so that the stimulation is steady and gentle rather than abrupt. Many guayusa enthusiasts describe this effect as “clean focus” – a sense of alertness without jitteriness.

According to scientific studies, guayusa infusions may support concentration, reaction time, and mental endurance during prolonged cognitive effort. Meanwhile, the presence of polyphenols and triterpenoids may support metabolic balance and immune function through antioxidant action – although these are not medicinal effects, but natural properties of the plant.

Ilex guayusa – properties:

• ✔️ Supports alertness and concentration – thanks to caffeine and theobromine, which stimulate without inducing the tension often associated with coffee.
• ✔️ Provides balanced energy – the combination of alkaloids and amino acids creates a long‑lasting, even lift.
• ✔️ Supports good mood – natural bioactive compounds may promote inner calm and emotional balance.
• ✔️ Contains antioxidants – polyphenols and triterpenoids protect cells from oxidative stress and support overall wellbeing.
• ✔️ May support healthy metabolism – scientific observations suggest that bioactive compounds in guayusa may assist natural metabolic processes.

Guayusa – contraindications

Like any beverage containing caffeine, guayusa should be consumed mindfully. Infusions from Ilex guayusa are recognised by the FDA as GRAS (Generally Recognised As Safe), and toxicological studies have not identified harmful effects at typical dietary doses. However, individual sensitivity to caffeine varies – what feels like pleasant stimulation to one person may cause difficulty falling asleep or palpitations in another.

Because of its caffeine content, guayusa is not recommended for certain groups. Caution is advised, especially for individuals:

• with caffeine sensitivity or conditions requiring reduced caffeine intake,
• with hypertension or cardiovascular issues,
• pregnant or breastfeeding, as caffeine may pass through the placenta and into breast milk,
• children and adolescents, whose nervous systems are more sensitive to stimulants.

Scientific reviews indicate that consuming guayusa may cause guayusa side effects such as elevated blood pressure, insomnia, or feelings of nervousness, although these are generally mild and dose‑dependent. In practice, moderate intake (around 1-2 cups per day) is well tolerated by most adults. Unlike coffee, guayusa rarely causes a sudden post‑caffeine crash, making it an appealing option for people with a sensitive nervous system.

It is also advisable to choose guayusa from reliable sources – free from artificial flavourings or additives that may affect tolerance. Pure, natural Ilex guayusa leaf infusion provides pleasant stimulation in a gentle and safe way.

How to brew guayusa tea to fully use its potential?

A perfectly brewed guayusa tea is more than just a drink – it is a morning ritual that helps you enter the day with clarity and energy. Although preparing the infusion is very simple, the brewing method matters: the temperature of the water and the steeping time determine both the flavour and the caffeine content in your cup. It is worth taking a moment to extract the full aroma and the gentle, balanced stimulation that guayusa offers.

Interestingly, you can brew guayusa in two ways – like classic tea or similarly to yerba mate. Each method creates a slightly different effect, so it is worth experimenting to find your favourite brewing ritual.

Guayusa – step-by-step brewing guide

The simplest way to brew guayusa does not require any special equipment. A mug, a tea infuser, or a French Press will do. Guayusa tea – how to brew it?

1. Add 2-4 teaspoons of dried leaves per 200-300 ml of water (depending on how strong you prefer your infusion).
2. Pour hot water (around 90°C – see below for details) and let it steep for 5-10 minutes.
3. Strain or remove the infuser, then enjoy the gentle, herbal taste of the infusion.

If you prefer a stronger stimulating effect and a more intense aroma, you can prepare guayusa as a boiled decoction – a traditional Amazonian method:

1. Use 2-4 tablespoons of dried leaves per 500 ml of water.
2. Boil gently for about 3 minutes, then strain through a sieve or filter.
3. The infusion will be stronger, darker in colour, and fuller in flavour.

One of the advantages of guayusa is that it can be re‑steeped – much like yerba mate. Each additional brew gives a milder, more herbal infusion.

Water temperature and steeping time for guayusa tea

To bring out the full flavour of guayusa, it is worth paying attention to the water temperature. Water that is too cool will not release the aromas, while water that is too hot may suppress some of the delicate flavour notes.

• Optimal water temperature: around 90°C – slightly higher than for yerba mate, but not boiling water straight from the kettle.
• Ideal steeping time: 5-10 minutes, depending on the desired flavour and strength.

A shorter steep (around 5 minutes) gives a mild, subtly stimulating drink – perfect for the afternoon. A longer steep (around 10 minutes) creates a more pronounced caffeine effect and a deeper, richer flavour. Guayusa does not become bitter even if steeped for longer, making it exceptionally forgiving – it is hard to “overbrew” it.

Guayusa – other brewing methods (hot, cold, cold brew)

One of the characteristics that sets guayusa tea apart from other herbal infusions is its versatility. You can prepare it not only hot, but also in chilled or cold‑brew versions – perfect for warm days.

• ✔️ Classic hot infusion: delivers a fuller flavour and a harmonious boost – ideal for chilly mornings.
• ✔️ Cold brew: add 3-4 teaspoons of guayusa to a container, cover with cold water, and refrigerate for 6-8 hours. The resulting drink is lighter, less caffeinated, and very refreshing.
• ✔️ Iced guayusa: brew traditionally, cool the infusion, then add ice, lemon, or fresh fruit – a natural alternative to energy drinks, light yet invigorating!

Cold-brewed guayusa tends to have a milder effect and a fresher, more botanical taste. In contrast, boiled guayusa produces a fuller, rounded flavour – perfect for long evenings.

How much guayusa to use and how often can you drink it?

The correct amount of dried leaves is crucial for a perfect infusion. Too little – and guayusa will taste weak. Too much – and the infusion may turn overly strong. The proven ratios are:

• 2-3 teaspoons of dried leaves per 250 ml of water for a classic infusion.
• 2-4 tablespoons of dried leaves per 500 ml of water if preparing guayusa by boiling.

Every body reacts differently, but for most people, drinking guayusa 1-2 times a day is optimal. Its effect is long‑lasting and does not require frequent refills – it provides steady energy without disrupting the body’s balance.
