MITO--Eight people who ate hydrangea leaves served as a trimming to a main dish at a restaurant in Tsukuba, Ibaraki Prefecture, suffered food-poisoning symptoms such as vomiting and dizziness, the Ibaraki prefectural government said Sunday.
Of the eight, one woman in her 30s and another in her 40s got medical attention at a clinic. Both are recovering well, according to the sources.
Hydrangea leaves contain a substance that produces hydrocyanic acid in reaction with stomach acids. Staff at the restaurant did not know the plant was toxic. One employee who was quizzed by a prefectural official is quoted as saying, "We used the leaves to add a seasonal touch."
According to the sources, a group of 19 people had dinner at Yushoku Itarian Fujiemon Sakae, a fusion restaurant, on June 13. Eight of the group later complained of sickness.
