Are osmanthus flowers edible?
Generally speaking, osmanthus flowers are edible. A detailed analysis is as follows:

Osmanthus contains abundant amino acids, vitamins, trace elements, and other nutrients. It helps relieve coughing, alleviate asthma, remove phlegm, and eliminate oral odor. Osmanthus is commonly used in making teas, pastries, and alcoholic beverages. Soaking osmanthus in hot water produces a fragrant tea that can refresh the mind and relieve fatigue. It can also be made into sweet and soft delicacies such as osmanthus cake and osmanthus biscuits. Additionally, osmanthus can be fermented with alcohol to produce a fragrant and smooth osmanthus wine, which may help improve blood circulation and relieve stress. However, it should be noted that osmanthus has blood-activating properties, so pregnant women should consume it cautiously to avoid stimulating uterine contractions and affecting fetal development. Furthermore, individuals allergic to osmanthus should avoid consuming it to prevent adverse reactions.
It is recommended to purchase processed osmanthus products from reputable vendors or to thoroughly wash and confirm the safety of self-harvested osmanthus before consumption, which contributes to maintaining good health.
