Birds eye chile pepper, also known as Thai chilis, is a tiny elongated pepper originating from Thailand and the neighboring countries. They’re primarily used in Southeast Asian cuisine, though they’re now common worldwide. These tiny chilis prefer hot climates and grow on small bushes in the wild, and are easily cultivated in the home garden.
What Is A Birds Eye Chili?
Birds eye chili peppers are thin, small, and pointed peppers that turn red when ripe. Some varieties ripen to a purple or orange, and any can be harvested and eaten when green for a less spicy and fresher flavor.
It is believed to have originated from Africa, Vietnam, The Philippines, Thailand, Cambodia, and the surrounding countries where it grows wild in African countries like Ethiopia.
Those known as Thai chiles originate from Southeast Asia, where the climate is hot. Birds eye peppers are bushy plants with narrow fruits with pods averaging five centimeters long with a diameter of around one centimeter. They’re known as Birds eye chili peppers because of their small pointed shape, and because they are spread by birds unaffected by the peppers’ heat.
They sometimes resemble the Serrano pepper, but the latter is rounder and fatter, while Birds eye chili is thinner.

Historically, they have been used as a natural remedy for flatulence, toothache, rheumatism, and arthritis and could have been used as insect repellents when mixed with water. They are also effective in treating inflammation due to the presence of capsaicin.
