Any idea if Carolina willow (Salix caroliniana) is safe? It does contain salicin which has similar effects as salicylic acid (a compound of aspirin). This is growing in my ditch and just about everyone else's ditch around here.
Edit: I found this after posting the question:
The objective of this study was to evaluate the nutritive content and in vitro dry matter digestibility (IVDMD) of
leaves, green stems, bark, and wood of Carolina willow (Salix caroliniana) used as browse for exotic herbivores.
One bundle of willow was harvested in April, August, September, and October 2003 (average = 6.82 kg fresh
weight, n = 4) and stored at 4.4 °C until sampled. Each bundle was separated into leaves, green stems, and woody
stems. The woody stems were divided into four diameter categories (< 0.5 cm, 0.5–1.0 cm, > 1.0–2.0 cm, and >
2.0 cm) and further separated into bark and wood. Each component was weighed and frozen for analysis of dry
matter (DM), crude protein (CP), acid detergent fibre (ADF), lignin, gross energy (GE), starch, minerals (Ca, P,
Mg, K, Na, Cu, Fe, Mn, Mo, and Zn), and IVDMD. Bundles averaged 5 % green stems, 20 % leaves, 21 % bark,
and 54 % wood on a dry matter basis. Leaves had the greatest and wood had the least CP content. Acid detergent
fibre was lowest in bark from stems less than 2 cm in diamter and greatest in wood. Bark from stems, greater than
0.5 cm in diamter, had the greatest Ca content with wood having the least. Phosphorus content was greater in
green stems than bark and wood from stems greater than 0.5 cm in diamter. Leaves had nearly fivefold greater Zn
concentration than wood. Bark, from stems less than 1 cm in diamter, had greater IVDMD than wood. As ADF
content of the browse components increased, their IVDMD decreased. Based on the extent to which each species
consumes willow browse components, the nutritive content varied, but could be a part of a balanced diet.
