Mulungu (Erythrina mulungu): Bark, Flowers, and What Varies

Mulungu is the common name for bark from Erythrina trees, most often Erythrina mulungu, native to Brazil. It has a long history in Brazilian folk practice and it now moves through the international botanical trade with the same loose labeling that affects most South American barks.

The Tree

Erythrina mulungu is a thorny flowering tree in the legume family, Fabaceae. It produces striking red flowers, which is why it is also planted ornamentally. The bark is the part traded, though the flowers are sold separately in smaller volume.

Species Confusion

Several Erythrina species are sold as mulungu, including Erythrina verna and Erythrina velutina. They are related but not identical, and Brazilian sources in particular use the common name across more than one species depending on region.

This is the first thing to establish. A listing that says only mulungu is telling you a regional name, not a species.

Bark Versus Flower

Bark is the standard product and what most preparation instructions assume. It is sold in shredded or powdered form. Flower is sold less often, usually dried whole, and is a different product with a different composition.

As with most barks, shredded material can be inspected and powder cannot. If consistency matters to you, buy shredded and mill it yourself.

Judging Quality

Good mulungu bark is uniform in color with minimal woody core mixed in. Bark and heartwood are not the same material, and a batch with a lot of pale woody fragments has been stripped carelessly.

It should smell faintly of dry wood rather than musty. A musty or sour smell means it was dried slowly in humidity or stored damp.

Preparation

The traditional preparation is a decoction, meaning the bark is simmered rather than steeped. Bark is dense and a short infusion in hot water pulls very little out of it. Twenty minutes at a low simmer is a common starting point.

Tinctures are the other common format and are easier to dose consistently than a decoction, since the extraction is done once at production rather than differently every time you make a cup.

Storage

Dry, sealed and out of light. Bark is one of the more forgiving materials to store because it is dense and low in volatile oils, but humidity will still get into it and powder degrades faster than shredded.

What to Ask Before Buying

Ask the species in full. Ask whether it is bark or flower, and whether the bark is trunk or root bark. Ask the origin and harvest year.
