Question

Give an example of a plant which came into India as a contaminant and is a cause of pollen allergy.

Answer 1

Hint: The distribution of pollen helps fertilize plants which can mean discomfort for people suffering from seasonal allergies.

Complete answer:
- Pollen is a thin, yellowish powder that is transferred by wind, insects, birds, or other organisms from plant to plant. When people breathe in pollen, several persons have an undesirable immune response.
- The immune system typically protects the body from infectious invaders to ward off pathogens, like bacteria or viruses. The immune system incorrectly views the innocuous pollen as a toxic intruder in persons with pollen allergies.
- To battle against the pollen, it starts to create chemicals. This is recognized as an allergic reaction, and an allergen is described as the particular form of pollen that triggers it.

The response leads to various symptoms that are annoying, such as:
- Shivering
- Congestion of nasal tract
- Stuffy nose
- Eyes Became Watery
- Throat and eyes itchy
- Wheezing

Asthma symptoms, like increased wheezing and coughing, can also be exacerbated by pollen.
Parthenium is a plant that induces pollen allergy.

Note: Some individuals have year-round pollen allergies, and others have pollen allergies only at certain periods of the year. For instance, when birch trees are in flower, individuals that are susceptible to birch pollen normally have increased symptoms mostly during spring. Similarly, throughout late spring and early autumn, people with ragweed allergies are mostly impacted.
