Study after study confirms that the body does not get the same benefit from vitamin and mineral supplements as it does obtaining nutrients from whole food sources. In other words, getting antioxidants by eating broccoli is much better than getting antioxidants from a tablet. Ashitaba Green is an organic whole food, certified by "California Certified Organic Farmers". The ashitaba (Angelica Keiskei Koidzmi) seeds are imported from Japan but these plants are grown and harvested in California. In order to maintain the plant's energy and maximize its unique qualities as an antioxidant and detoxicant, no extraction methods are used in the processing of Ashitaba Green. At Natural Health Organic Farm, the Hayano's (Koidzumi-Hayano) have developed a pathogen-free (low bacterial count) processing plant. Freshly harvested ashitaba plants are treated as Whole Food, with leaves and stems dried together so that the plant does not lose its natural, beautiful green color. Ashitaba Green contains no additives.
