Translate this page:


Pau Brasil, Caesalpinia echinata, is a slow-growing small tree up to 12 m high found in South America. It has a large rounded crown and the branches, leaves, and fruits are thorned. When fully established, it is drought-tolerant. Bark is powdered and used as treatment for diarrhoea in children. Pods and wood are sources of black dye and red dye (brazilin), respectively. The wood is heavy, tough, hard, and durable and is used for turnery, building ship and making musical instruments like bows for violins. Other common names include Brazil Wood and Pernambuco tree. Common names: Brazilwood, Pernambuco tree. Portuguese: Pau-Brasil, Pau de Pernambuco; Tupi Ibirapitanga.

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antidiarrhoeal  Odontalgic  Tonic

A charcoal made from the powdered bark is infused and used to treat diarrhoea in children[ 307 ]. The wood is odontalgic and tonic[ 739 ].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses

Charcoal  Dye  Hedge  Wood

Other uses rating: High (4/5). Seaside, Small flowering Tree, Accent, Screening, Barrier, Large planter, Xerophytic. Agroforestry Uses: Plants can be trimmed to keep them small and dense[ 307 ]. This gives them potential for use as barrier plants[ 307 ]. Other Uses An infusion of the pods, mixed with iron sulphate, yields a permanent black dye[ 307 ]. A red dye is obtained from the wood[ 46 ]. It becomes purplish when mixed with alkalis and yellow if mixed with acids[ 46 ]. A fiery red colour, the dye was a very important item of trade until virtually replaced with synthetic dyes[ 349 ]. The heartwood is red-brown to dark brown; it is clearly differentiated from the thin layer of sapwood. The wood is fine-grained, very tough, hard, heavy and very durable[ 46 , 307 , 419 ]. Very dense, it sinks in water, is easy to split and to polish[ 46 ]. Of high value, the wood is used for turnery, ship building and making musical instruments[ 46 , 307 ]. It is particularly valued for making bows for violins[ 349 ].

Cultivation details

Prefers a well-drained, alkaline soil and a position in full sun[ 307 ]. Established plants are very drought tolerant[ 307 ]. Plants are fairly tolerant of salt-laden winds[ 307 ]. A moderately fast-growing tree, reaching a height of up to 2 metres within 2 years from seed[ 419 ]. Plants begin to flower when around 3 - 4 years of age[ 349 ]. The development of heartwood in plantation trees is considerably faster than in the wild; the DBH of a 17 year old plantation tree compares with a 70 year old tree in the wild[ 349 ]. The quality of wood from plantations is, apparently, not suitable for making violin bows and consequently there is a lack of interest in growing the species in plantation[ 349 ]. The flowers are very attractive to bees[ 307 ]. Trees in the wild are frequently covered with orchids and other epiphytes[ 349 ]. Plants in this genus are notably resistant to honey fungus[ 200 ]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[ 200 ].

Seed - pre-soak for 12 - 24 hours in warm water prior to sowing. Sow the seed in a partially shaded position in individual containers. A germination rate in excess of 60% can be expected, with the seed sprouting within 8 - 15 days[ 419 ]. When the seedlings are 4 - 6cm tall, pot them up into individual containers and they should be ready to plant out 4 - 5 months later[ 419 ]. Seeds must be sown fresh, they fail to germinate after storage for 30 days[ 349 ]. Softwood cuttings in sand in a frame[ 200 ]. This plant may be considered a protected species; check before digging or gathering seeds.
