Siling labuyo is a small chili pepper cultivar native to the Philippines. It belongs to the species Capsicum frutescens and are characterized by triangular fruits which grow pointing upwards.[1] The fruits and leaves are used in traditional Philippine Cuisine. The fruit is very hot, ranking at 80,000 to 100,000 SHUs in the Scoville Scale.[2]

The cultivar name is Tagalog, and literally translates to "wild chili."[1] It is also known simply as labuyo or labuyo chili.[3] It is also sometimes known as Filipino bird's eye, to differentiate it from the Thai bird's eye chili. Both are commonly confused with each other in the Philippines, though they are cultivars of two different species.[4]

Siling labuyo is one of two common kinds of native chili found in the Philippines, the other being siling haba. Unlike siling haba, it belongs to the species Capsicum frutescens.[5]

Siling labuyo is listed in the Ark of Taste international catalogue of endangered heritage foods of the Philippines by the Slow Food movement.[6]

Taxonomy and names[edit]

Siling labuyo is officially known under the cultivar name Capsicum frutescens 'Siling Labuyo'. It belongs to the species Capsicum frutescens. Related cultivars to 'Siling Labuyo' include 'Tabasco', 'Malagueta', and 'African Birdseye'.[1]

The common name is Tagalog for "wild chili", from sili ("chili") and the enclitic suffix -ng, and labuyo ("growing wild", also a term for wild chicken or junglefowl).[1][7] Other local names for it include chileng bundok, siling palay, pasitis, pasite (Tagalog), katumbal, kutitot, siling kolikot (Bisaya), silit-diablo (Ilocano), lada, rimorimo (Bicolano), and paktin (Ifugao).[8]

Commonly confused cultivars[edit]

Red bird's eye chili are commonly mislabeled as siling labuyo in Filipino markets. But they are actually a chili pepper cultivar from a different species (Capsicum annuum) that came by way of Thailand. Their fruits, unlike C. frutescens, are borne on the plant drooping down.[4] In Luzon, siling tingala, a high-yield F1 hybrid of C. frutescens and C. annuum from Taiwan are also commonly sold as siling labuyo. While they have C. frutescens ancestry (the fruits are also borne erect), they are much longer and uniformly red, very similar to Thai bird's eye chilis. They are also sterile and do not propagate on their own in the wild, requiring farmers to buy seedlings after every harvest.[9]

Both the bird's eye chili and siling tingala are popular with retailers because their color and shape are more consistent and they have a longer shelf life, but they are regarded as less spicy than siling labuyo.[1][9][10]


Like other Capsicum frutescens cultivars, siling labuyo has a compact habit, growing between 1 to 4 ft (0.30 to 1.22 m) high. They have smooth ovate to lanceolate leaves that are around 2.5 in (6.4 cm) in length with pointed tips. They produce small greenish-white flowers with purple stamens. These develop into a large number of small, tapering fruits that are around 0.6 to 1 in (1.5 to 2.5 cm) in length. The fruits are very pungent and are characteristically borne erect (pointing upwards). Immature fruits are deep green in color and usually ripen to a vivid red, but other varieties can have yellow, orange, white, purple, or even black fruits. Flowers and fruits are often clustered in groups of 2 to 3 at a node.[1][11][12]

Siling labuyo fruits are small but are very hot. It measures around 80,000-100,000 Scoville units which is at the lower end of the range for the hotter habanero chili.[2] At one time it was even listed as the hottest chili in the Guinness Book of World Records but other hotter varieties of chili have since been identified.

Ingredient in cooking[edit]

Although not as central in Filipino cuisine as bird's eye chilies are in other cuisines of Southeast Asia, it is still an often-used ingredient. The fruit of siling labuyo is popularly used to flavor vinegar to be used as a spicy condiment, while its leaves are usually consumed as a vegetable, such as in the dish tinola.[1][13]

Other uses[edit]

In medicinal terms, the labuyo fruit was earlier utilized as an herbal plant to ease arthritis, rheumatism, dyspepsia, flatulence, and toothache.[13]

It can also be used as a natural insect repellent or pesticide when mixed with water.[14][15]
