Capparis zeylanica, commonly known as Ceylon caper or Indian caper, is a woody climbing shrub native to tropical Asia, including Sri Lanka. Recognised in Sri Lanka's catalogue of Ayurvedic medicinal plants, it has been used in traditional healing systems for centuries. The plant belongs to the family Capparaceae and is found growing in dry and intermediate zone forests, scrublands, and along roadsides across the island.
What does Capparis zeylanica look like?
The plant is a scrambling or climbing shrub that can reach several metres in height when supported by surrounding vegetation. Its stems bear short, hooked thorns that help it cling to trees and other structures. The leaves are simple, ovate to elliptic, and arranged alternately along the stem.
Flowers are white to pale pink, with prominent, long, brush-like stamens that give them a delicate, showy appearance. They typically open at night and are pollinated by moths and other nocturnal insects. The fruit is a berry-like capsule, reddish when ripe, containing seeds embedded in a reddish pulp.
Where does Capparis zeylanica grow in Sri Lanka?
This species thrives in the dry zone and intermediate zone of Sri Lanka, where it commonly appears in scrub forests, hedgerows, and disturbed habitats. It is well-adapted to seasonally dry conditions and poor soils, making it a resilient component of lowland dry-forest ecosystems.
Ecologically significant dry-zone areas such as those surrounding Wilpattu National Park represent the kind of habitat where this species naturally occurs alongside other dry-zone flora. It also grows in the drier parts of the North Central Province and along the coastal plains.
What are the traditional Ayurvedic uses of Capparis zeylanica?
In Sri Lankan and broader South Asian Ayurvedic practice, multiple parts of Capparis zeylanica are used medicinally. The plant is known in Sinhala as Welangiriya and in Sanskrit as Vyaghranakhi or Gridhrasi. Different traditions ascribe distinct therapeutic actions to its roots, bark, leaves, and fruit.
- Root bark: Traditionally used in formulations intended to address rheumatic and musculoskeletal complaints, and as an ingredient in preparations for neurological conditions.
- Leaves: Applied externally as a poultice or paste in folk remedies for skin conditions and localised pain.
- Fruit: The ripe berries have been used in preparations for digestive complaints, and the seeds contain oils with reported antimicrobial properties in ethnobotanical literature.
- Stem and root: Included in certain classical Ayurvedic compound formulations targeting vata-related disorders, including joint stiffness and nerve pain.
In classical Ayurvedic texts, Capparis zeylanica is typically classified under plants with tikta (bitter) and katu (pungent) tastes, with heating properties considered beneficial for conditions attributed to excess vata and kapha doshas.
How is Capparis zeylanica used in Ayurvedic formulations?
The plant features as a component in several traditional polyherbal preparations. Its root bark is an ingredient in classical formulations such as Kaishore Guggulu variants and similar compound remedies targeting inflammatory and musculoskeletal conditions. It is also referenced alongside other dry-zone medicinal plants like Acacia chundra and Pongamia pinnata in Sri Lankan ethnobotanical surveys.
In contemporary Ayurvedic pharmacy in Sri Lanka, the plant is sourced primarily from wild populations in the dry zone, as large-scale cultivation remains limited. Sustainability concerns have grown as demand for Ayurvedic raw materials increases, prompting interest in managed cultivation of species like Capparis zeylanica.

Does Capparis zeylanica have any recorded pharmacological properties?
Modern phytochemical research has identified several classes of compounds in Capparis zeylanica that may help explain its traditional uses. Studies have reported the presence of alkaloids, flavonoids, terpenoids, and glucosinolates — a class of compounds characteristic of the Capparaceae family and known for various biological activities.
Preliminary research (largely in vitro and animal model studies) has explored potential anti-inflammatory, analgesic, antioxidant, and antimicrobial activities of plant extracts. However, robust clinical trials in humans remain limited, and the plant should be used only under the guidance of a qualified Ayurvedic practitioner. Findings from published botanical research should not be taken as medical advice.
How does Capparis zeylanica relate to Sri Lanka's Ayurvedic heritage?
Sri Lanka has one of the oldest continuous traditions of Ayurvedic medicine in Asia, with a documented pharmacopoeia that draws heavily on the island's diverse native flora. The government maintains an official list of medicinal plants through the Department of Ayurveda, and Capparis zeylanica holds a place in this recognised catalogue.
The plant is part of a broader ecosystem of traditional knowledge that connects Sri Lanka's forests, its farming communities, and its centuries-old healing traditions. Other well-known Sri Lankan medicinal and botanical species documented by Lakpura include Syzygium aromaticum (cloves) and Ceylon black pepper, both of which share roots in the island's long history as a source of prized botanical commodities.
Conservation of species like Capparis zeylanica depends on maintaining the dry-zone forest habitats where they are native. Sustainable wildcrafting practices, combined with growing interest in cultivating medicinal plants, are key to preserving this heritage for future generations.
