Special instructions:

Generally speaking, it is not suitable for pregnant women to keep flowers and plants at home, because the fragrance of flowers will hurt pregnant women. This is because the strong fragrance of flowers may stimulate the nerves of pregnant women, causing headaches, nausea and vomiting, and affecting appetite. In severe cases, it may also lead to fetal instability and even abortion. Moreover, pollen generally contains certain chemical components. If it falls on the skin or is inhaled into the respiratory tract, it may cause allergies, and strong floral fragrance is more likely to aggravate allergic symptoms. Therefore, for pregnant women with sensitive skin and respiratory tract, it is not an exaggeration to call the rich floral fragrance "disaster". Hydrangea belongs to poisonous flowers and trees. Its whole plant is poisonous. Although the flower is beautiful, as long as it touches it, it will give off an unpleasant smell. So it is also called "smelly hydrangea". Based on the above reasons, it is suggested that pregnant women at home should not breed hydrangeas.
