The Medicinal Plants of Costa Rica and How They Shape a Wellness Experience on the Pacific Coast

Long before wellness became an industry, Costa Rica’s forests were already doing the work. The plants growing along the Pacific Coast’s riverbanks, rainforest edges, and kitchen gardens have been part of local healing traditions for centuries.  

This guide covers eight of them, what they are, where they grow, and why the Pacific Coast remains one of the most quietly compelling destinations for travelers who take this seriously. 

Why Costa Rica Is One of the Most Plant-Rich Countries on Earth 

Costa Rica occupies just 0.03% of Earth’s land surface yet holds an estimated 5% of the planet’s total known species, a ratio the Royal Botanic Gardens Kew describes as one of the most remarkable in global ecology.  

Positioned between North and South America, flanked by two oceans, and layered with volcanic mountain ranges and coastal rainforest, the country became a biological bridge and never stopped accumulating species. 

Over 300 medicinal plant species are actively used in communities across the country, a figure that reflects daily practice across communities.  

These plants appear in garden beds, along trails, and on market stalls from Guanacaste to the Osa Peninsula. 

Eight Plants the Pacific Coast Has Always Known About 

Note: The following reflects traditional and historical use only and does not constitute medical advice. Consult a qualified health professional before using any plant-based remedy. 

These plants grow in gardens, along roadsides, and in the kitchens of Pacific Coast communities. They have simply been here longer than the wellness industry has. 

1. Guanabana / Soursop (Annona muricata) 

Medicinal property: Fever relief, inflammation, and digestive support 

The guanabana tree grows throughout the Central and Southern Pacific, recognisable by its large spiny green fruit that looks like it was designed by someone who had never seen a fruit before.  

Costa Rican communities have used it in teas and preparations for fever, digestive complaints, and inflammation, documented by the TRAMIL network.  

It is the kind of tree that grows in a backyard and gets taken completely for granted until someone from outside the country asks what it is. 

2. Moringa (Moringa oleifera) 

Medicinal property: Energy, immunity, and nutritional tonic 

Moringa grows quickly, needs little encouragement, and produces leaves and seeds that Pacific Coast communities have used for generations as a nutritional and energising tonic.  

Sometimes called the miracle tree in wellness circles, its traditional use for supporting energy and immunity is well documented.  

On the Pacific Coast it appears quietly, growing beside vegetable plots and farm fences. 

3. Curcuma / Turmeric (Curcuma longa) 

Medicinal property: Anti-inflammatory, joint pain, and digestion 

Turmeric is the plant that stains everything it touches, including cutting boards, fingers, and the reputations of anyone who dismisses it as a trend. Its traditional anti-inflammatory use across Central America predates every wellness café that has put it on a menu by several centuries.  

The TRAMIL network documents its use for joint pain and digestive complaints. In Costa Rica it appears in both home gardens and the growing farm-to-table wellness scene along the Pacific. 

4. Noni (Morinda citrifolia) 

Medicinal property: Immune support and natural pain relief 

Noni is the fruit that coastal Pacific communities have used for generations despite the fact that it smells, diplomatically speaking, like very ripe cheese.  

Documented by the National Center for Complementary and Integrative Health for its traditional use in immune support and pain relief, noni occupies an interesting position in plant medicine: widely used, effective according to those who use it, and deeply unappealing to first-time visitors who encounter it by smell before sight. 

5. Zarzaparrilla (Smilax domingensis) 

Medicinal property: Joint pain relief and general body tonic 

Zarzaparrilla is a climbing vine that moves through the Pacific lowland forest with quiet persistence, used traditionally as a general tonic and for joint pain across Central America.  

You will find it growing along secondary forest edges within an hour of Los Sueños, used by communities who have been making preparations from its root for longer than anyone can trace.  

6. Dormilona (Mimosa pudica) 

Medicinal property: Sedative, nerve calm, and muscle tension 

Touch a leaf of the dormilona and it folds inward immediately, closing like someone caught reading in bed at midnight.  

The name translates to sleeping lady, which is either a coincidence or the most accurate plant name in the tropics, because the same mechanism that makes the plant retract from touch mirrors its traditional use as a sedative.  

Costa Rican healers have prescribed it as a tea and tincture for centuries to ease insomnia, calm nerve pain, and release muscle tension.  

7. Manzanilla / Camomile (Matricaria chamomilla) 

Medicinal property: Digestive relief, restlessness, and sleeplessness 

Camomile in Costa Rica needs no introduction.  

It is in every home, every grandmother’s kitchen, and every small tienda from Jacó to Uvita. Pacific Coast communities reach for it at the first sign of a stomachache, a restless night, or a child who will not settle.  

The most ordinary plant in this list is also the most consistently used, which makes it something more interesting than ordinary. 

8. Cilantro (Coriandrum sativum) 

Medicinal property: Digestive aid and anti-inflammatory support 

Cilantro hides its medicinal credentials behind its culinary ones. In Costa Rica it is as fundamental to cooking as salt, appearing in gallo pinto, ceviche, and almost every sauce from a Pacific Coast kitchen.  

Traditional healers across Central America have used cilantro tea for digestive complaints and as an anti-inflammatory remedy for centuries.  

Papaya seeds, from the same domestic kitchen tradition, have been used separately as a digestive tonic across the region. Two plants hiding in plain sight in every Costa Rican home. 

How These Plants Shape Wellness Experiences on the Pacific Coast 

Here is how they translate into experiences worth building a trip around. 

Botanical Garden Visits 

• What they offer: Guided tours through medicinal plant collections with local naturalists who identify, name, and explain the traditional use of each species. 

• Access: Botanical gardens near the Central Pacific are free to visit, among the most accessible introductions to Costa Rica’s plant heritage available to travelers. 

• What to expect: A slow walk through a living inventory of healing flora, best experienced with a guide who knows which plant is which before you have to ask 

Rainforest Wellness Walks 

• What they are: Guided jungle walks with local naturalists identifying medicinal flora along Pacific Coast trails, available through eco-lodges and wellness operators near Jacó and Los Sueños 

• The difference a guide makes: The same trail walked alone and walked with a local naturalist are two entirely different experiences. One is a hike. The other is a conversation with the forest. 

• Arranging one: Half-day guided experiences can be arranged through the villa’s concierge 

Farm to Table Herbal Cuisine 

• The connection: Pacific Coast chefs and private cooks have incorporated medicinal herbs into seasonal menus long before the term farm to table existed 

• In practice: Turmeric in broths, cilantro as both flavour and function, guanabana in fresh preparations, moringa leaves alongside market vegetables 

• The point: Traditionally, many Pacific Coast ingredients have served both culinary and wellness roles. 

What Wellness Travelers Should Know Before Visiting 

Engage Responsibly 

The most effective way to engage with Costa Rica’s plant medicine traditions is through certified local guides and established wellness operators.  

Self-administering plant remedies without expert guidance is inadvisable. Some tropical species require precise preparation, and the knowledge behind traditional use has been developed over generations for good reason. 

Best Time for a Wellness Trip 

• Dry season (December to April): Most consistent conditions for outdoor botanical walks, garden visits, and rainforest excursions 

• Green season (May to November): The forest at its most lush, crowds thinner, Pacific light more dramatic

A Week Well Spent on the Pacific Coast 

Villa Firenze at Los Sueños is a fully private base with a concierge who knows the coast, a private chef who cooks with the seasons, and a yoga and wellness amenity built into every stay. 

Concierge also arranges guided rainforest walks and botanical excursions for guests who want to go further than the terrace.  

The private chef shapes daily menus around what is fresh and local, which on the Pacific Coast means medicinal herbs appear on the plate the same way they appear in the forest: quietly, doing more than one thing at once. 

A week here gives you the time and the base to go deeper than a day tour ever could. Discover what a wellness day at Villa Firenze looks like.  

The Forest Has Always Known What It Was Doing 

Costa Rica’s medicinal plants have been working quietly along the Pacific Coast for centuries, in home gardens and rainforest trails, in morning teas and evening meals, in the hands of healers who spent fifteen years learning what the rest of the world is only beginning to ask about. 

For wellness travelers who stay long enough to explore them, the Pacific Coast offers something genuinely rare. 

Villa Firenze is where that week begins.
