Which plants and flowers should not be placed in a pregnant woman's room?

Some floral fragrances can stimulate a pregnant woman's nerves, and some pollen can trigger allergies. Therefore, pregnant women should be cautious about keeping flowers indoors.
Strong floral fragrances may stimulate a pregnant woman's nerves, causing headaches, nausea and vomiting, and affecting her appetite; in severe cases they may even cause fetal restlessness or even miscarriage.
So during early pregnancy, it is best for pregnant women to have as little contact as possible with fresh flowers that have strong scents, and best not to place such plants and flowers in the bedroom.
In addition, pollen generally contains certain chemical components, and if it lands on the skin or is inhaled into the respiratory tract, it may trigger allergies.
Coniferous and cypress plants: including daphne (Daphne odora) and elderberry (Sambucus), whose fragrant scent irritates the stomach and intestines, not only affecting appetite but also making the expectant mother feel restless, nauseous and vomiting, and dizzy.
Oleander (Nerium oleander): secretes a milky white liquid; with prolonged contact it can cause poisoning, leading to adverse reactions such as drowsiness and reduced mental acuity.
Orchids and lilies: their fragrance can make people overly excited and affect the expectant mother's sleep quality.
Chinese rose (Rosa chinensis): kept indoors for a long time, the scent it gives off can cause the expectant mother to feel short of breath and depressed.
