An Ayurvedic name usually arrives with a part attached. The texts do not simply say Arjuna; they say the Twak, the bark. Specifying the part is not a detail, it is half the identification.
What Twak means
Twak is the term for bark, the layer taken from the trunk rather than the root that is dug or the fruit that is picked. Within the materia medica you will meet Mula (root), Phala (fruit), Patra (leaf), Pushpa (flower), Beeja (seed) and Niryasa (resin), and a formula that names a plant is understood to mean the part the tradition specifies for it.
Why it matters
Two preparations can name the same plant and contain quite different material. Reading a label therefore means reading two things: which species, and which part. A bark and a fruit from one tree are not the same ingredient.
How it reads on a label
Arjuna Capsules state Terminalia arjuna bark. The same logic runs through the range: Tagara Capsules state root and rhizome, and Harida Capsules state rhizome, because Haridra is dug rather than picked.
Frequently Asked Questions
Is bark always the part used for Arjuna?
The classical texts name the bark, and that is the material offered here.
Why do some labels not say the part?
They should. Without it the species alone does not fully describe the ingredient.
What is the Sanskrit for root?
Mula, as in Dashamula, the ten roots.
