Benzamidine is a reversible competitive inhibitor of trypsin, trypsin-like enzymes, and serine proteases. [4] It is often used as a ligand in protein crystallography to prevent proteases from degrading a protein of interest. The benzamidine moiety is also found in some pharmaceuticals, such as dabigatran.

The Caribs made arrow poison from its sap. [15] The wood is used for furniture under the name "hura". In a time when most writing pens left wet ink on the page, the trees' unripe seed capsules were sawn in half to make decorative boxes (also called pounce pots) to hold the "sand" used to dry it, hence the name 'sandbox tree'.

The gum is yellowish and may be either clear or opaque. It darkens deeply as it ages, and white streaks emerge. [3] Myrrh gum is commonly harvested from trees of the genus Commiphara.
