The main content I'm excited to add to the updated guide are the histories behind each plant (which cultures used these plants and for what? do they still use them now? what modern medicines are/have been derived from these plants?) and the active chemical compounds that make them competitive plants and effective medicines.
The updated guide will also include more species profiles, detailed botanical drawings for every species included, and new maps of where/which herbs are growing abundantly now in Central Park.
Below is a sample page from the current guide on Japanese Knotweed, also known as "tiger cane" in Chinese medicine. You've probably come across this elegant and super-resilient plant in parks and backyards. Most of the ones I'm seeing around NYC are about 5 to 6 feet tall now!
