Light micrograph of a Cannabis sativa germinated seed: the outer protective hard shell of the mature seed splits off, and a tiny, white sprout or radicle pops out, we can see too developed root hairs (lateral extensions of a single cell). Hemp fibre, medicinal drugs, marijuana, hashish and hash oil are obtained from the plant. It is one of the 50 fundamental herbs of Traditional Chinese Medicine and the only plant that produces cannabinoids (approximately 40 of them) which have numerous well-documented beneficial effects: stimulation of hunger in chemotherapy and AIDS patients, decrease of intraocular pressure, analgesic, antispasmodic, antibacterial and expectorant. It is also a potential treatment for Alzheimer's disease, Myasthenia Gravis, multiple sclerosis, gastrointestinal illness, depression and glaucoma. Field of view size: 9.0 x 13.5 mm (0.35 x 0.53 in)
