Alfalfa is an excellent forage crop when harvested and stored properly. However, the plant can cause “hepatogenous photosensitivity syndrome” if water-damaged.

Toxic Principle:
The toxic principle of this plant is uncertain. It is possibly the quinolizidine alkaloid, cytisine, which acts like nicotine.

Poisoning Symptoms include:
Hepatogenous photosensitivity syndrome, a clinical condition in which skin (areas exposed to light and lacking significant protective hair or pigmentation) are hyper-reactive to sunlight due to the presence of photodynamic agents. Molecules of photosensitizing agents present in the skin are energized by light. When the molecules return to the less energized state, the released energy is transferred to receptor molecules that quickly initiate chemical reactions in various skin components. Tissue injury is thought to result from the production of reactive oxygen intermediates or from alterations in cell membrane permeability. Photosensitization can be difficult to differentiate clinically from actual sunburn.
