• Source: Always ensure that any edible flowers you consume are from a reliable source and have not been treated with pesticides or other chemicals.

• Identification: Be absolutely certain of the flower's identification before consuming it, as many ornamental flowers are toxic.

• Allergies: If you have allergies to pollen or specific plants, introduce edible flowers into your diet cautiously.

• Nutrient Density: While these flowers contain calcium, they are generally consumed in smaller quantities than other calcium-rich foods like dairy or leafy greens. They should be considered a complementary addition to a balanced diet.
