What triggers allergy this month?
There are many flowering plants in May. Many of them do not induce allergic reaction.
May being Asthma Awareness Month, we examine the allergens
that induce asthma attack during this month for example Logustrum.
Ligustrum is a common hedge plant often used in landscape developments. The shrub grows to a height of about 20 feet and is identified by its oval leaves. Ligustrum is in bloom during the month of May in Southern United States, carrying white flowers with pleasant smell. It may bloom in early summer in the northern region.
There are different species of ligustrum, Ligustrum lucidum,
Ligustrum japonicum, Ligustrum obtusifolium, Ligustrum ovalifolium, Ligustrum quihoui, Ligustrum sinense, and Ligustrum vulgare.
Many individuals are allergic to ligustrum pollen. When inhaled it can trigger symptoms of a runny nose, blocked nose, itchy eyes, cough and wheezing.
