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.

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, 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 can be used for tannin extraction.

Traditional Chinese Medicine (info from this website)

In Taiwan, A. confusa was used as a traditional medicine. The aqueous extract of A. confusa leaves was applied to cure wounds and antiblood stasis. The commercial and industrial uses of A. confusa were fire wood, charcoal-making, railroad tie, mining construction and mushroom cultivation. For water and soil conservation, this plant is planted in the wilderness for a long time because its root system is extremely strong and can grow extensively and deeply into the ground. Recently, this plant has shown great potential for air pollution prevention because of its remarkable carbon dioxide sequestration ability and foliar dust retention. The bark and wood of A. confusa, like many other Acacia species, are rich in tannins which are used to dye and stain clothes and tan leather.

Once the package arrives in the US, the USPS take over the shipping. Orders can be tracked with the tracking tool found at Free shipping: There is no tracking available for this reliable, but slower shipping method. Packages ship with PostNL and then are handed over to the USPS and deliveries may take up to 30 days. This option is not always available, depending on what you are ordering and where you are shipping to. Registered via NY: Depending on which state you are shipping to, this option will be available in order to try and ensure that there are no delays to your package as it enters the US. Packages are shipped first of all with PostNL to a NY forwarding address and then, from there, shipped on to you. We will update you on the tracking once your order is shipped from the Netherlands and then again once it is forwarded from NY.  Updates can take up to 24 hours because we work in different time zones around the world.
When you place an order in our web shop, you will automatically see the shipping options that are available, depending on your cart contents and the US state you are shipping to. For different states we use different methods.
Free Shipping from USA: For customers ordering only our Mimosa hostilis Hidden Valley and/or Mexican MHRBs, we have also established a warehouse that will exclusively ship to our customers from within the US.  This has the advantage of offering tracked shipping without having to pass through customs and a delivery time of only 3-4 working days. Orders will be shipped with USPS Priority mail.  This service is available for Mimosa only orders.  Any other products will need to ordered separately and will be shipped from the Netherlands.   Good to know: All of our orders are packed and shipped discreetly with only the obligatory information such as shipping and return address on the outside. Registered orders outside of Europe are sent with PostNL who hand your order over to the national postal service of your country. For instance in the US, packages are handed over to the USPS. Registered orders within Europe are sent with DPD. Fast and trackable at all times. Our Free shipping option is slow(er) but very reliable too. Estimated shipping time for outside Europe is between two to four weeks depending on postal flows.
For valuable orders we would advise choosing the Registered option.
