Question

What is the best time to collect the medicinal bark material?

• A. Post flowering
• B. Before the leaf falls
• C. Pre flowering
• D. After the leaf falls

Hint:

- Medicinal bark should be harvested after leaf fall to maximize phytochemical concentration. - Avoid collection during active growth phases (flowering, pre-flowering) when nutrient transport is high. - Low sap flow during dormancy makes drying and preservation easier.

Answer 1

The Correct Option is D

The best time to collect medicinal bark is after the leaf falls, as this ensures that the plant is in its dormant phase, reducing stress and damage. During this period, the active phytochemical compounds are at their highest concentration, and there is minimal sap flow, making the bark easier to peel and store. Collecting the bark at other stages is less effective. 
Post-flowering (A) is a phase where the plant directs its resources to seed production, resulting in lower medicinal compound concentration. Before the leaf falls (B), the tree is actively transporting nutrients, leading to a higher moisture content in the bark. Pre-flowering (C) is another phase where the plant is focusing on bud and flower formation rather than storing medicinal compounds in the bark. 

Thus, harvesting bark after the leaves have fallen ensures maximum potency and better preservation of medicinal properties.
