Kadukkai is Terminalia chebula, the chebulic myrobalan — one fruit of the triphala trio, with amla and thanrikkai. The dried fruit is ridged, tan to black, and astringent. It does not sell a “detox.”

How to recognise Kadukkai
Retzius published Terminalia chebula. The family is Combretaceae. It is a tree with opposite or subopposite leaves and spikes of small pale flowers. The useful part in trade is the drupe, five-ribbed when dry.
Tamil kadukkai, Hindi harad and Sanskrit harītakī are the same fruit when the seller is honest. Large and small grades in a bazaar are still this species if the stone and ribs match.
Terminalia bellirica (thanrikkai, bibhitaki) is the sister fruit in triphala: usually rounder, less sharply ribbed. Terminalia arjuna is a different tree used for bark, not this fruit.
Fresh fruit is yellowish and inedible in the casual sense — people dry it. Once it is in a churna, only the formula and a mill you trust stand between you and a cheaper astringent.
Kew treats the species as accepted. A “myrobalan” without a Latin name could be any Terminalia fruit in old European trade.
Grades in a bazaar (big, small, black, yellow) are still this species if the five ribs and the stone match. Colour after drying tracks ripeness and kiln heat, not a different tree.
Whole fruit you can split is the identification. Once it is a fine churna in a triphala tin, only the mill’s word stands between you and a cheaper astringent.
Traditional use of Kadukkai
Ayurveda
Harītakī is a rasāyana fruit and one third of triphala. Traditional qualities (astringent, laxative in that system’s language) are historical descriptions.
Ayurvedic pharmacopoeial trio
Siddha and Tamil practice
Kadukkai is a household and vaithiyar fruit, used whole, powdered, or as a wash. Food-as-medicine talk around it should stay inside that tradition, not become a disease claim.

Modern notes on Kadukkai
Tannin-rich fruits are easy to study in a beaker and hard to turn into a responsible human claim.
Triphala research, when it exists, is about a mixture. It does not let a single fruit inherit every headline.
Quality problems are the practical modern story: immature fruit, insect-bored lots, and substitution with other Terminalia.
Tannin content varies with harvest time. That is a mill fact. It is not a reason to print a disease name on a pouch.
Kadukkai safety
Dried fruit is strongly astringent and, in some people, loosening. That is a reason to be modest with dose, not a selling point.
Pregnant people and children should not be put on triphala or haritaki from a blog.
Anyone with loose stools already should not treat this fruit as harmless fibre.
Ecology and sourcing
The tree is wild and planted in dry deciduous forest and village lands. Fruit collection can be sustainable if trees are left standing.
