Vinca alkaloids have been generally included in combination chemotherapy regimens for medicinal therapies. They do not have cross-resistance with drugs that alkylate DNA and have a different mechanism of action. They have been used to treat diabetes, high blood pressure and have been used as disinfectants and anti-cancer. (Moudi, et al., 2013)

Let me warn you here – High dosages of this flower or its leaf can cause instant drop in blood sugar levels and is hence consume a small amount periodically for gradual decrease in sugar levels.
Pregnant women with Gestational diabetes are strictly warned against the use of this tea.
Periwinkle is also a toxic plant and high doses may have poisonous effects. Hence do not drink this tea unless you have consulted with a natural medicine practitioner. Clearly inform the practitioner regarding all your current medications so that he can suggest the suitable course of action.
