The common sunflower (Helianthus annuus L.) is an annual plant, native from Minnesota to Texas and California and also found in Central and South America. Aboriginal peoples cultivated the plant and found many uses for it. The flower petals were traditionally used as a tea for treating breathing problems, high fever and as a diuretic. The astringent tea was also used externally for treating acne, insect bites and other wounds. The main use of sunflower, however, is as a source of nutritious food. Sunflower seeds are extremely rich in the amino acid arginine (8.2% or 332mg/tbsp), which, according to Naturopaths, is important for countering low sperm counts. It is recommended that men get approximately 4 grams of arginine per day to boost low sperm counts. Sunflower seeds are also rich in phenylalanine (161mg/tbsp), shown in human studies to reduce pain perception. Human and animal studies show that phenylalanine makes acupuncture more effective at reducing pain. In laboratory animals, phenylalanine also enhanced the effect of morphine and made it last longer. Sunflower seeds are also very rich in glutamine (771 mg/tbsp) � an important amino acid precursor for glutathione, said by medical researchers to be the most important self-made antioxidant in the human body. Taking glutamine boosts blood levels of glutathione much better than taking glutathione directy because glutathione doesn’t get transported between cells whereas glutamine does. In one animal study, supplementing with glutamine caused a 40% increase in glutathione levels. In a study with humans suffering from inflammation, blood glutathione levels jumped 20% after subjects took 5-15 grams of glutamine daily. The normal recommendation for glutamine is 2 – 8 grams per day. Sunflower seed and meal is also rich in linoleic acid (omega-6 Essential Fatty Acids � polyunsaturates), oleic acid (omega-9 � monosaturates) and Vitamin E.
