Elixirs should be stored in which type of containers?

• A. In nightlight-resistant containers with protection from excessive heat
• B. In clear glass bottles at room temperature
• C. In metal containers without light protection
• D. In plastic bags

Answer: (A)

Elixirs are often light-sensitive and can degrade when exposed to light or heat. Storing them in containers that block light and protect from excessive heat helps preserve potency and stability. Amber or nightlight-resistant glass keeps light from triggering photochemical reactions, while shielding from heat minimizes evaporation and breakdown of ingredients. Clear glass would let light penetrate and heat exposure could occur; metal or plastic containers without proper light protection can lead to reactions or leaching and don't reliably shield the contents. So the best option is a container that protects against both light and excessive heat.
