Acacia confusa | ACRB

Our Acacia confusa root bark comes from Taiwan. Farmers collect it from trees which fall down in the rainy season.

Native use

The original peoples of Taiwan may have traditionally used ACRB as an entheogen. Chinese medicine practitioners use it today. They say that the old herbalists believed that ACRB can take you to another world.

It seems to be suitable for ayahuasca analogues but so far there is limited experience with these preparations. Some research reports successful ayahuasca preparations and direct oral activity using the root bark and trunk bark.

We call ayahuasca analogues made with Acacia confusa bark Formosahuasca. This word comes from formosa acacia which means beautiful acacia. This may refer to Ilha Formosa, the beautiful island, the original Portuguese name for Taiwan. Another name is Chinahuasca or Asian Ayahuasca.

You can use ACRB together with Syrian rue, B. caapi or B. muricata. Recently, people have found that you can also use it alone.

Most people prefer to work with MHRB Mimosa hostilis root bark.


Acacia confusa belongs to the Leguminosae (Pea family). Acacia confusa is a perennial tree native to South-East Asia. Some common names for it are Acacia Petit Feuille, Small Philippine Acacia, Formosa Acacia (Taiwan Acacia) and Formosan Koa. Acacia confusa grows to a height of 15 meters. The tree is now very common in many tropical Pacific areas, including Hawaii, where the species is invasive. Acacia confusa wood has a density of about 0.75 g/cm³. In Taiwan, they use this wood to make support beams for mines. They also convert it to charcoal for family use. In Taiwan, people use acacia confusa in traditional medicine. You can buy it in herbal medicine shops (草藥店).

Scientific information

ACRB contains high concentrations of noteworthy alkaloids in its root and trunk bark.

The wood and bark are very rich in tannins. People use these tannins to dye and stain things, for example animal hides (leather). The stem bark of Acacia confusa contains between 23-35% tannins. A tree of about 30cm diameter at chest height gives approximately 10-20kg of raw dried bark that you can use for tannin extraction.
