Katupila (Flueggea leucopyrus Willd.) is a hardy shrub that grows across the dry lowlands of Sri Lanka and parts of South India. Long valued in Sri Lanka's traditional systems of medicine, it has attracted growing interest from researchers studying its phytochemical properties, particularly in relation to its historical use as an anti-tumour remedy. The plant is modest in appearance — a much-branched, spiny shrub that can grow to about 5 metres tall — yet its leaves, roots, bark, and fruit have all found a place in Ayurvedic and Sinhala indigenous practice.
What does Katupila look like and where does it grow?
Flueggea leucopyrus belongs to the family Phyllanthaceae (formerly placed within Euphorbiaceae). It is an erect, much-branched woody shrub up to about 5 metres tall, with small, rounded green leaves up to about 2.5 cm long. Its angular branchlets end in sharp spines, which the Sinhala name reflects: katu means thorn. Male and female flowers grow on separate plants; they are small, greenish and barely larger than a peppercorn. The fruit is a round berry about 5 mm across that turns white when ripe, which is why the plant is known in English as Indian snowberry or white honey shrub.
In Sri Lanka the shrub is found predominantly in the dry and arid zones, in scrub land and on sandy coastal plains. Districts where it grows naturally include Mannar, Puttalam, Hambantota, Anuradhapura, Polonnaruwa, Matale, and Ampara. Beyond Sri Lanka it grows in India and other parts of South and Southeast Asia, and in East Africa, in scrub and dry deciduous forest from sea level to about 900 metres.
What are the traditional and Ayurvedic names for this plant?
The plant carries several names across different medical traditions, reflecting the breadth of its historical use:
- Sinhala: Katupila, Heen Katupila
- Tamil: Vellaipoola
- Sanskrit: Panduphali, Bhuriphali
- English: Indian snowberry, white honey shrub
- Common misspelling: Flugguea leucopyrus
Some sources give Sharapunkha, with a list of related Sanskrit synonyms, as the Ayurvedic name of Katupila. In Ayurveda, Sharapunkha is a different plant, Tephrosia purpurea (wild indigo), so that name should not be used to identify or buy Katupila.
Traditional Sri Lankan descriptions give the plant a bitter taste (tikta rasa) with light, dry and sharp qualities — properties that guide its use in traditional preparations.
How is Katupila used in traditional Sri Lankan medicine?
Traditional practitioners work with the whole plant — leaves, bark, roots, flowers, and seeds — often collectively referred to as the panchanga (five parts). The preparations described below reflect long-standing indigenous practice and should not be treated as medical advice; consult a qualified Ayurvedic or medical professional before use.
Common traditional preparations
- Decoction (kadatura): Leaves and bark are boiled in water and the strained liquid is consumed, sometimes combined with honey or other herbs such as curry leaves or samanpichcha.
- Leaf porridge: Fresh leaves are cooked into a thin gruel. In some formulations, kuburu leaves and curry leaves are added.
- Curry: Young leaves are prepared as a side dish with lentils — a common way to incorporate the plant into the daily diet in dry-zone villages.
- Leaf juice: Ground fresh leaves are squeezed to extract juice, which may be mixed with buffalo milk or other carriers depending on the intended use.
- Root extract: The root is sometimes combined with other plant extracts — for example, Pota vine juice or raw turmeric — in preparations targeting specific conditions.
- Commercial herbal tea: Dried and processed Katupila leaf is now available as a packaged herbal tea in Sri Lankan markets, positioned as a general wellness drink.
What conditions is Katupila traditionally associated with?
Indigenous and Ayurvedic texts mention Katupila in the context of several health conditions. The most frequently cited traditional uses are summarised below. These are historical and ethnobotanical observations — not clinically verified treatments.
| Condition (traditional context) | Plant part typically used | Common carrier or adjuvant |
|---|---|---|
| Tumour / cancer-related conditions | Whole plant panchanga | Honey, curry leaves, samanpichcha |
| Intestinal ulcers | Leaves and tender stalks | Honey (taken in the morning) |
| Uterine fibroids | Root extract | Pota vine juice, raw turmeric |
| Haemorrhoids | Leaves | Buffalo milk, hemp leaves |
| Liver complaints | Leaf decoction | Pepper powder |
| Musculoskeletal or lower-back conditions | Leaves, bark, flowers, roots | Yellow salt (ground together) |
Is there scientific research on Flueggea leucopyrus?
Most research on Flueggea leucopyrus comes from Sri Lanka and South India, and so far all of it has been done in the laboratory or on animals. In a 2014 Sri Lankan study published in BMC Complementary and Alternative Medicine, a water extract of the leaves showed strong antioxidant activity and, at relatively high concentrations, killed human laryngeal cancer cells grown in the laboratory. The authors noted that cancer patients in Sri Lanka drink the leaf decoction as a supplement alongside their conventional treatment. Other laboratory studies have tested extracts on breast and ovarian cancer cells, and a 2024 study in rats, published in Antioxidants, found that leaf and root extracts reduced inflammation. Screening of the plant has found alkaloids, terpenoids, flavonoids, tannins and other phenolic compounds. No clinical trial has tested Katupila as a cancer treatment in people.
Anyone being treated for cancer should tell their doctor before taking Katupila in any form, because herbal preparations can interact with other treatments. The studies can be found by searching the PubMed Central database for Flueggea leucopyrus.
How does Katupila fit into Sri Lanka's broader herbal heritage?
Sri Lanka's dry zone has long been a living pharmacopoeia. Villages in Anuradhapura, Mannar, and Hambantota districts have maintained oral traditions around plant medicine for generations, often preserving knowledge not fully documented in classical Sanskrit or Pali texts. Katupila is one of several understory shrubs — alongside plants such as Sida species and various Cassia relatives — that form the backbone of this grassroots healing tradition.
The plant's resilience — it survives harsh dry-season conditions with minimal water — mirrors a wider pattern in Sri Lankan ethnobotany: some of the island's most pharmacologically interesting plants grow in the most challenging environments. Conservation of dry-zone scrub habitat is therefore not only an ecological concern but also a cultural one, as the disappearance of these landscapes would mean the loss of medicinal plant populations that communities have depended on for centuries.
Can Katupila be grown in a home garden?
The shrub is relatively easy to cultivate in warm, low-humidity conditions with well-drained sandy or loamy soil — conditions that mimic its native dry-zone habitat. It tolerates drought once established and generally does not require irrigation beyond the early growth stage. It is not suited to wet-zone climates with heavy year-round rainfall, where waterlogged soil is likely to cause root stress. Propagation is typically from seed, though stem cuttings can also be used.
