Jeruk pecel (Citrus aurantiifolia)

Citric acid is the primary organic component in this fruit, responsible for its sharp sour taste while also acting as a natural preservative and mucus-dissolving agent. In its peel, dominant essential oils such as D-limonene and citral provide strong antimicrobial activity along with a refreshing aroma. The fruit is also rich in vitamin C, an essential antioxidant for collagen synthesis and enhanced immune response. Additionally, flavonoids such as hesperidin and naringin help strengthen capillary walls and reduce inflammation.

Citric acid acts as a natural throat soother with effective mucolytic properties that help thin thick phlegm and clear the respiratory tract, making this fruit commonly used as a traditional remedy for coughs. Additionally, it supports detoxification and digestive health by stimulating bile production, neutralizing toxins in the stomach, and relieving nausea. When applied to the skin, its antibacterial and acidic properties help control excess oil, tighten pores, and combat acne-causing bacteria. Its high vitamin C content also makes it a natural immune booster that helps the body fight flu infections and mild inflammation.
