Functions
1. Anti-cancer effect
Both vinblastine and vincristine have anti-cancer effects.
2. Antihypertensive effect
Intravenous injection of Catharanthus roseus total alkali has a hypotensive effect on anesthetized cats and rabbits. The blood pressure drops rapidly, which is different from the slow blood pressure lowering of Rauwolfia total alkali preparations. The blood pressure reduction is accompanied by deepening of breathing and the amplitude becomes larger; Cutting off the vagus nerve or using atropine does not affect its antihypertensive effect. Total base also has the effect of dilating coronary blood vessels (it is an antispasmodic ganglion blocking agent).

Foreign folk use periwinkle leaves and whole plants to treat diabetes. Vinblastine, epoxyvinblastine, vinblastine and tetrahydrofuranine isolated from Catharanthus roseus all have varying degrees of hypoglycemic effects, starting slowly but lastingly. The aqueous extract of the leaves can also lower blood sugar in normal and alloxan-induced diabetic rabbits and dogs.
4. Diuretic effect
