Though the fruit is edible, it is rather insipid when eaten raw. A tea can be made of the flower or leaves; however, tetraphyllin B and epi-tetraphyllin B,  [[cyanogenic glycoside]]s which liberate [[hydrogen cyanide]] when activated by enzymes, have been found in the leaves. It is possible to boil away most of the cyanide.<ref name="tetraphyllin b">DS Seiglera, KC Spencera, WS Statlerb, EE Connb, JE Dunnb, '[http://www.sciencedirect.com/science/article/pii/0031942282851911 Tetraphyllin B and epitetraphyillin B sulphates: Novel cyanogenic glucosides from Passiflora caerulea and P. alato-caerulea]', ''Phytochemistry'', 21/9 (1982), 2277-2285.</ref>
