Open an Ayurvedic cabinet and you will find the genus Terminalia three times over, usually without noticing, because the classical names do not advertise the botany.

The three

  • Arjuna, Terminalia arjuna, of which the bark is used.
  • Haritaki, Terminalia chebula, a fruit.
  • Bibhitaki, Terminalia bellirica, also a fruit.

Two of those three are members of Triphala, the classical group of three fruits. The third member of Triphala, Amalaki (Phyllanthus emblica), is not a Terminalia at all.

Different parts, different preparations

The genus is shared; the material is not. Arjuna contributes bark, the other two contribute fruit, and the texts treat them as quite distinct. Botanical relation is not interchangeability, which is worth saying plainly because the shared genus sometimes invites the assumption.

Where they appear in the range

Arjuna Capsules are the bark of Terminalia arjuna. Triphala Capsules carry the classical three-fruit group, two thirds of which is Terminalia. The Triphala guide covers that group in full.
