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. In hot teas, it is used to treat sore throats, fevers, diarrhea, colds, flu, pneumonia, asthma, and coughs, as well as a mild nerve sedative, a diuretic, and an antispasmodic.
There are many other benefits from raising rabbits. Rabbit manure is considered one of the best available. It contains more nitrogen and phosphorus than many other manures and more potash than most. Even when applied fresh, it will not burn plants. Gardens with rabbit fertilizer consistently applied most often yield much better results than without. It is also a great component for your compost. Some nurseries may even offer to purchase your rabbit manure.
