While Russian comfrey (Symphytum x uplandicum) can contain a crude protein content ranging from 15% to nearly 30% on a dry matter basis, its significant nutritional value is reserved exclusively for animal feed, as the plant is highly toxic to humans. This plant's impressive nutrient profile is overshadowed by severe health risks associated with its consumption.

Leucaena leaves, from the fast-growing 'miracle tree' *Leucaena leucocephala*, are a highly nutritious forage crop that can contain up to 34% crude protein in dry matter. Beyond their value as animal feed, these leaves offer significant benefits for soil enrichment and may even hold medicinal properties for human use.
