What are the benefits of flowers to the human body?

Flowers can be used as health food for banquets and family dining tables, or as medicine, or extracted from pollen nectar to keep fit and prolong life. Although flowers have many benefits to health, we should also pay attention to prevent mosquito pollution and pesticide poisoning when planting flowers. It is not advisable to plant too many flowers indoors. When plants grow, photosynthesis occurs during the day, and oxygen is absorbed at night to release carbon dioxide, which reduces indoor oxygen, which may lead to aggravation or recurrence of patients with hypertension, coronary heart disease and pulmonary heart disease.
