Two forms of vitamin A are available in the human diet: preformed vitamin A (retinol and its esterified form, retinyl ester) and provitamin A carotenoids [1-5]. Preformed vitamin A is found in foods from animal sources, including dairy products, fish, and meat (especially liver).
Rabbit tobacco can be used medicinally in several ways. Smoking the leaves is good for sinusitis, head colds, and congestion.
