Chechem (pronounced "chay-CHEM") is a hard, dense wood from Mexico, Central America and the British West Indies with an unusually moderate specific gravity that produces a surprisingly lower tone than you might expect.
Chechem (aka Black Poison Wood) is very hard and dense and resistant to wear. It is often used as a substitute for Brazilian rosewood. The bark of the tree secretes a caustic sap that can cause a painful rash like poison ivy.
Bone Rattling Facts
Chechen is a popular choice for snare drums. It is also well suited for hand-held musical instruments because Chechen is very durable, slightly oily, and resistant to rot and insect attack. The wood is not harmful to you. Only the sap and sanding dust are toxic. So you can safely rattle bones made of Chechen with no ill effects. Then again, you can add this wood to your collection just to prove that you live dangerously."

Chechen is part of the Anacardeiaeae family, which includes cashews, pistachios, mangoes, poison oak, poison ivy, and poison sumac.
- It is a preferred material for railroad ties.
- It's alternate name is black poisonwood from the toxic sap that turns black and causes severe skin reactions. Wiki reports that "The Mayans still tell stories of poisoning the water supplies of Yucatecan soldiers with chechen during the Guerra de las Castas in the mid-1800s."

(Banana Fudge Ripple)
The heartwood is dark reddish brown with dark brown stripes and lighter streaks. The color is somewhat similar to Black walnut, although the color can vary widely.
The sapwood is yellowish brown and clearly distinct from the heartwood.
There is no characteristic odor, smell or taste.
The wood is safe to handle. But don't inhale the sanding dust which can cause dermatitis and respiratory issues. Chechem is an easy wood to work, although interlocking grain can cause problems when planing or surfacing. Nails and screws should be pre-drilled because this very dense wood tends to split. Glues and finishes well.
Chechem is available from environmentally responsible or sustainably managed sources. The Nature Conservancy reports that "Although the species may be quite rare in parts of its range, especially at the periphery, it is reported to be rather abundant, and secure globally." The lesser-known species, Black Poisonwood, is a possible substitute for some of the more exotic and endangered species.
The species is reported to occur in Central America, Latin America, North America, Oceania and S.E. Asia.
Chechem grows to the size of a shrub or a fairly tall tree reaching a height of about 50 feet (15 m) with a trunk diameter of about 21 inches (50 cm).
