Guava Leaves

Guava leaves come from the Psidium guajava, a tropical plant widely grown across Indonesia. While the fruit is popular, the leaves have long been valued in traditional Indonesian practices for their medicinal and practical uses. In Indonesia, guava leaves—locally known as daun jambu biji—are commonly used in herbal remedies (jamu). They contain bioactive compounds such as flavonoids, tannins, and antioxidants, which contribute to their health benefits. The leaves are typically prepared by boiling them into a decoction or crushing them for topical application.

Natural dyeing material

Guava leaves are traditionally used as a plant-based dye because they contain tannins and polyphenols that bind well to fibers.

• Color produced: Typically soft shades of brown, beige, olive green, or gray, depending on processing.

• Textiles: Commonly applied in natural dyeing of cotton, silk, and batik fabrics.

• Mordanting: When combined with mordants like alum, iron, or lime, the color can shift:

  • Iron → darker gray/black tones

  • Alum → lighter beige/yellowish tones

• Traditional context: In Indonesian textile crafts (including eco-print and batik), guava leaves are valued because they are abundant and environmentally friendly.
