Cusco sits at 3,399 meters (11,152 ft) above sea level, and altitude sickness is one of the most common concerns for travelers visiting the region. One of the most traditional and widely used remedies in the Andes is coca leaf tea, known locally as mate de coca.
But does coca leaf tea really help prevent altitude sickness?
Is it safe and legal for tourists?
And what do local guides actually recommend?
In this updated 2026 local guide, we explain everything you need to know—based on real experience guiding travelers in Cusco, not generic medical advice.
What Is Altitude Sickness in Cusco?
Altitude sickness (also called soroche) happens when your body struggles to adapt to lower oxygen levels at high altitude. It usually appears within the first 24 hours after arrival.
Common symptoms include:
- Headache
- Nausea
- Dizziness
- Fatigue
- Shortness of breath
- Loss of appetite
These symptoms are very common for travelers arriving directly from sea level.
What Is Coca Leaf Tea?
Coca leaf tea is an herbal infusion made from natural coca leaves, a plant traditionally used by Andean cultures for centuries to cope with altitude, cold, and physical exhaustion.
Important clarification:
Coca leaves are NOT cocaine.
They are a natural plant used legally in Peru for traditional purposes.
Does Coca Leaf Tea Really Help with Altitude Sickness?
From a local guide’s experience: YES, it helps—but it’s not magic
Coca leaf tea may:
- Improve oxygen absorption
- Reduce headaches and nausea
- Increase energy levels
- Help digestion at altitude
However, it works best when combined with proper acclimatization and smart travel planning.
Most hotels in Cusco offer coca tea for free because locals see it as first-line support, not a cure.
What Does Science Say About Coca Leaf Tea?
Some scientific studies suggest that coca leaves may help reduce altitude discomfort by improving oxygen absorption and circulation. However, results vary by person, and coca tea should be considered a traditional support, not a medical treatment.
How Locals Use Coca Leaf Tea in Cusco
As local guides, this is what we recommend to travelers:
- Drink 1–2 cups per day during your first days
- Drink it warm, especially in the morning or evening
- Combine it with rest and light meals
- Avoid drinking it late at night
Locals don’t rely only on coca tea—they respect the altitude.
Is Coca Leaf Tea Legal for Tourists?
In Peru: YES
Coca leaf tea is 100% legal to drink, buy, and consume within Peru.
Outside Peru: NO
Coca leaves cannot be taken abroad.
Never carry coca tea bags in your luggage when leaving the country.
Hotels and tour operators will always remind you of this.
Coca Leaf Tea vs Other Altitude Remedies
| Remedy | Effectiveness | Local Recommendation |
|---|---|---|
| Coca leaf tea | Moderate | Yes |
| Acetazolamide (Diamox) | High | Only if prescribed |
| Oxygen tanks | Short-term | Emergency use |
| Hydration & rest | Essential | Yes |
| Alcohol | Harmful | ❌ Avoid |
Coca tea is a natural support, not a substitute for medical treatment.
When Should You Drink Coca Leaf Tea?
The best moments are:
- Your first day in Cusco
- Before sleeping on your first night
- After arriving from a flight
- Before light walking tours
For high-altitude hikes (Humantay lake , Rainbow Mountain), coca tea alone is not enough.
Altitude Tips from Local Guides (Very Important)
To truly avoid altitude sickness:
- Spend 1–2 days acclimatizing in Cusco or Sacred Valley
- Walk slowly, no rushing
- Eat light meals
- Avoid alcohol the first 48 hours
- Stay hydrated
- Combine coca tea with rest
This is why many travelers start with Sacred Valley tours, which are at a lower altitude than Cusco.
Tours That Help with Acclimatization
From experience, these tours are ideal for your first days:
- Cusco City Tour
- Sacred Valley Tour
- Maras & Moray
- Short walking tours
We do NOT recommend doing Humantay Lake or Rainbow Mountain on your first day.
Is Coca Leaf Tea Enough for Everyone?
No.
Some travelers are more sensitive to altitude.
If symptoms worsen (severe headache, vomiting, confusion), seek medical attention immediately.
Coca tea is preventive, not a cure.
Why Booking with a Local Agency Matters
Local agencies understand:
- How altitude affects travelers daily
- When to adjust itineraries
- When to recommend rest vs pushing forward
This local knowledge makes a huge difference in your experience.

Coca leaf tea is:
- Natural
- Raditional
- Widely used

But the best protection against altitude sickness is planning your itinerary wisely.
