The Healing Gardens of Ceylon: Endemic Herbs of Sri Lanka in Ayurveda and Deshiya Wedakama

Sri Lanka, known historically as Ceylon, possesses extraordinary biodiversity with approximately 3,000 plant species, of which over 25% are endemic to the island. These native botanical treasures form the cornerstone of Sri Lanka's unique approach to Ayurveda and its indigenous medical tradition, Deshiya Wedakama. For millennia, these endemic plants have provided healing remedies that are uniquely tied to Sri Lanka's cultural and natural heritage.

Sri Lanka's Endemic Medicinal Flora: A Unique Healing Tradition

While classical Ayurveda originated in India and spread throughout South Asia, Sri Lanka's isolated geography as an island allowed its medical traditions to evolve distinctly, incorporating endemic plants found nowhere else on earth. Deshiya Wedakama (indigenous Sri Lankan medicine) particularly values these unique plant species, creating herbal preparations that are exclusive to Sri Lankan healing traditions.

Remarkable Endemic Herbs of Sri Lanka

Binkohomba (Munronia pinnata)

One of Sri Lanka's most treasured endemic medicinal plants, Binkohomba is considered a miracle herb in Deshiya Wedakama. This small, rare plant grows primarily in the island's central highlands and is known for its extraordinary bitter principle.

Traditional uses include:

• Treatment of resistant fevers and malaria

• Management of diabetes and blood sugar disorders

• Powerful anti-inflammatory for joint conditions

• Liver protection and detoxification

• Immune system enhancement

Due to overharvesting and habitat loss, Binkohomba is now critically endangered and protected by conservation efforts.

Weniwel (Coscinium fenestratum)

This endemic woody climber with its distinctive yellow stem is highly valued in Sri Lankan medicine. Though similar species exist in other parts of Asia, Sri Lanka's variety contains unique phytochemical profiles.

Traditional practitioners use it for:

• Treating infectious diseases, particularly those with fever

• Managing inflammatory conditions

• Healing wounds and skin disorders

• Supporting digestive function

• Reducing blood sugar levels

The stem's distinctive yellow color comes from berberine, a compound now studied extensively for its antimicrobial properties.

Kokum (Garcinia quaesita)

Endemic to Sri Lanka's wet zone forests, this relative of mangosteen produces a distinctive fruit with a thick rind that is dried and used medicinally. Its sour flavor is prized in both medicine and cuisine.

In traditional medicine, it addresses:

• Digestive disorders, particularly bloating and indigestion

• Obesity and metabolic conditions

• Inflammatory joint issues

• Skin conditions

• Excess kapha conditions according to Ayurvedic principles

The dried rind is often made into a soothing digestive tea or incorporated into curries for both flavor and health benefits.

Sudu Handun (Santalum album var. zeylanicum)

The Sri Lankan variety of sandalwood is botanically distinct from Indian sandalwood, with different aromatic properties and medicinal applications. This endemic variety grows primarily in Sri Lanka's dry zones.

Traditional uses include:

• Cooling preparations for pitta imbalances

• Treatment of urinary tract infections

• Skin conditions including rashes and infections

• Heart health support

• Mental clarity and meditation support

The heartwood and essential oil are particularly valued for both medicinal and ceremonial purposes.

Walla Patta (Gyrinops walla)

This endemic tree produces agarwood (a resinous heartwood) when infected with a specific fungus. While prized in perfumery, its medicinal properties are equally significant in Sri Lankan medicine.

Traditional applications include:

• Respiratory conditions including asthma and bronchitis

• Digestive disorders, particularly those with inflammation

• Nervous system complaints including anxiety

• Joint and rheumatic conditions

• Spiritual healing practices and protection

Conservation efforts are now in place to protect this tree from overharvesting due to the high value of agarwood in international markets.

Aralu (Terminalia chebula var. zeylanica)

The Sri Lankan variety of Aralu differs from the continental species, with unique properties recognized in traditional medicine. It's one of the three fruits in the famous Triphala formulation but possesses distinctive characteristics in its Sri Lankan form.

It's traditionally used for:

• Digestive regulation and detoxification

• Treatment of respiratory conditions

• Management of diabetes and metabolic disorders

• Eye diseases and vision support

• Rejuvenation therapies (Rasayana)

The fruit is prepared in various forms, from decoctions to powders, depending on the condition being treated.

Wal Kurundu (Cinnamomum citriodorum)

Wild cinnamon is distinct from cultivated Ceylon cinnamon (Cinnamomum zeylanicum) and possesses unique properties valued in traditional medicine. This endemic variety grows in Sri Lanka's interior forests.

Traditional uses include:

• Management of respiratory conditions

• Treatment of urinary disorders

• Relief from digestive discomfort

• Addressing vata imbalances

• Circulatory support

The bark and leaves are both used medicinally, with different preparation methods for various conditions.

Traditional Harvesting and Conservation Wisdom

Sri Lankan traditional medical texts contain specific instructions for sustainable harvesting that have helped preserve these plants for centuries:

• Collecting medicinal plants during specific lunar phases

• Harvesting only mature plants and leaving younger specimens

• Taking only what is needed and expressing gratitude

• Replanting and caring for medicinal plant populations

• Observing seasonal restrictions for certain species

These ancient conservation methods demonstrate the deep ecological understanding embedded within traditional knowledge systems.

Modern Research on Sri Lanka's Endemic Medicinal Plants

Scientific investigation increasingly validates the traditional uses of Sri Lanka's endemic medicinal plants:

• Research at the University of Peradeniya has identified novel compounds in Binkohomba with significant antimalarial properties

• Studies on Weniwel have confirmed its effectiveness against certain antibiotic-resistant bacteria

• Clinical trials with standardized extracts of Kokum have shown promising results for metabolic syndrome

• Phytochemical analysis has revealed unique compounds in Sri Lankan endemic plants not found elsewhere

This research not only validates traditional knowledge but also highlights the importance of preserving Sri Lanka's botanical heritage as a potential source of new medicines.

Preserving Sri Lanka's Endemic Medicinal Heritage

The endemic medicinal plants of Sri Lanka represent an irreplaceable resource for health and wellbeing. As habitat loss and climate change threaten these unique species, conservation efforts are essential:

• Botanical gardens dedicated to endemic medicinal plants

• Seed banks preserving genetic diversity

• Documentation of traditional knowledge

• Sustainable cultivation programs

• Community-based conservation initiatives

By protecting these plants and their associated knowledge systems, we ensure that the unique healing tradition of Sri Lanka continues to benefit future generations.
