This month, the Makiling Botanic Gardens features a plant that might assault your nose before catching your eye: kantutan (Paederia foetida L.), a vine from the Rubiaceae family with a pungent reputation and a long history of traditional uses across Asia.
A Name That Tells a Story
The scientific name of this plant offers an interesting contradiction. The genus name (the first part of the scientific name) Paederia comes from the Greek word “paederos,” meaning “opals”—those beautiful, colorful gemstones. However, the species name (the second part of the scientific name) “foetida” comes from the Latin word meaning “stinky” or “foul smelling.” This unusual pairing of beauty and odor captures the plant’s dual nature perfectly.
Identifying Features
Kantutan is a vine with smooth stems (the botanical term is glabrous) commonly found in thickets at low to medium elevations. The leaves are dark green, arranged oppositely along the stem, and slightly heart-shaped at the base with a pointed tip. They are smooth and covered with short, fine hairs. The plant’s most distinctive characteristic becomes apparent when the leaves are crushed—they release a strong sulfuric odor that explains the “foetida” part of its name.
The flowers grow in clusters called sessile cymules. The calyx (the outer part of the flower, made up of sepals) is small and toothed, covered with very fine, short, soft hairs. The corolla (the petals of the flower) is funnel-shaped or cylindrical, grayish white on the outside and dark purple on the inside—a striking color combination that rewards closer inspection.
The fruits are rounded, globe-shaped, and range from greenish to yellow in color.
Wide Distribution Across Asia
Kantutan is native to an extensive range across Asia, including the Philippines, Andaman Island, Assam, Bangladesh, Borneo, Cambodia, China, Hainan, Himalaya, India, Japan, Java, Korea, Laos, Lesser Sunda Island, Malaya, Maluku, Myanmar, Nansei-shoto, Nepal, Nicobar Island, Sri Lanka, Sulawesi, Sumatra, Taiwan, Thailand, Tibet, and Vietnam. This wide distribution reflects the plant’s adaptability and its integration into various traditional medicine and food systems across the region.
Culinary Applications
Despite its pungent smell, kantutan has found its way into traditional cuisines. In India, young leaves are boiled and eaten with chili and salt. In Hainanese cuisine, the leaves are ground into flour and mixed with rice to make noodles, and also made into soups.
Extensive Medicinal Uses
Kantutan has one of the most diverse arrays of medicinal applications among traditional Asian plants, with different parts of the plant addressing different ailments:
Leaves:
- Boiled in water and applied to the abdomen for excess gas, urinary retention, urinary bladder stones, antirheumatic baths, and to lower fevers
- Used as an astringent, and for treating diarrhea in children, scalding, and burns
- Applied as a paste to treat herpes
- Young shoots are used to relieve body pains after childbirth
- Paste of leaves mixed with the paste of other specific plants is used as an antidote for snake bites
Bark:

- Used for expelling gas
Fruit:
- Used to blacken teeth and to prevent toothache
Roots:
- Used to treat stomach cramps, spasms, liver inflammation, rheumatism, and gout
A Plant of Contradictions
Kantutan embodies fascinating contradictions: a plant named after beautiful opals yet known for its foul smell; a vine that repels with its odor when crushed yet attracts with its two-toned flowers; a species avoided by many yet sought after for its healing and culinary properties.
When you encounter kantutan at the Makiling Botanic Gardens or along the trails of Mount Makiling, take a moment to appreciate this multifaceted plant. While you might be tempted to give the crushed leaves a sniff out of curiosity, be prepared for the sulfuric odor that gave the plant its species name. Yet remember that this same plant has sustained communities across Asia for generations, providing both nourishment and medicine.
As our Plant of the Month for February 2026, kantutan reminds us that plants cannot be judged by first impressions alone. What seems unpleasant at first encounter may hold valuable properties that have been recognized and utilized by traditional knowledge systems across continents. (Article, photo, and video by For.
