Candle Nut (Aleurites moluccanus) is a tropical tree native to Southeast Asia and the Pacific Islands, thriving in humid, tropical climates. It plays a significant role in agroecological systems as a mid-canopy layer in food forests, providing shade and habitat for understory plants and wildlife. The tree improves soil fertility through its nutrient-rich leaf litter and acts as a windbreak, protecting more delicate plants. Traditionally, Candle Nut has been used by indigenous cultures for its oil, which serves culinary, medicinal, and lighting purposes. The tree is also valued for its timber and as a source of natural dyes. In regenerative agriculture, it is often integrated into guilds with nitrogen-fixing plants like pigeon pea (Cajanus cajan) and ground covers such as sweet potato (Ipomoea batatas) to enhance soil health and biodiversity.
Growing Details
Candle Nut trees thrive in well-drained, loamy soils with a pH of 5.5 to 6.5. Prior to planting, enrich the soil with organic compost and mulch with straw or wood chips to retain moisture and suppress weeds. Companion planting with nitrogen-fixing species like pigeon pea can enhance soil fertility. Avoid overwatering, especially in clay soils, to prevent root rot. Harvest nuts when they fall naturally, and store them in a cool, dry place to prevent rancidity.

Uses & Benefits
Edible Rating:
(2/5)
edible uses: The nuts are edible only when cooked, as raw nuts are toxic. They are often roasted and used in traditional dishes, particularly in Indonesian and Hawaiian cuisines. The oil extracted from the nuts is used for cooking and as a condiment.
Medicinal Rating:
(3/5)
medicinal uses: Candle Nut oil is traditionally used in some cultures for its anti-inflammatory properties and to treat skin conditions such as eczema and psoriasis. It is also used in massage oils for its soothing effects.
health concerns: The raw nuts are toxic due to the presence of saponins and phorbol esters and must be cooked thoroughly before consumption to avoid poisoning.
other uses: The oil extracted from the nuts is used for lighting and as a wood preservative. The tree provides valuable timber and is used in traditional crafts and construction.
