Esthetics Core Written Practice Test

If a client is allergic to aspirin, what ingredient should be avoided?

1. Rosemary extract

2. Willow bark

3. Aloe vera

4. Chamomile

The correct answer is: Willow bark

The correct response indicates that willow bark should be avoided if a client is allergic to aspirin. This is because willow bark contains salicin, a compound that is chemically similar to salicylic acid, which is derived from aspirin. Individuals with an allergy to aspirin may also react adversely to willow bark, as it can trigger similar allergic responses. In contrast, rosemary extract, aloe vera, and chamomile do not share this relationship with aspirin and are not known to cause similar allergic reactions. Rosemary extract is often used for its antioxidant and anti-inflammatory properties, aloe vera is well-regarded for its soothing and moisturizing effects, and chamomile has calming and anti-inflammatory benefits. Therefore, these ingredients would typically be safe for a client with an aspirin allergy, while willow bark poses a risk due to its chemical similarities.
