Spilanthes Acmella is an amazing herb now known as Oleracea Acmella. I have had great success growing it outdoors in Sweden and Vermont. It needs sun, warmth and water. For the last 2 years it has held a small place in the greenhouse where it thrives. We eat the potent leaves regularly as we work in the greenhouse and the tiny unique flower buds are a powerhouse of medicinal uses. Famous for it’s healing effects in the mouth including toothache, gum disease, blisters and sores. This year I experimented and discovered a way to preserve the flower heads that makes dosage strength easier to control and the drying process uniform without so much loss of potency you get when drying the whole heads. I make my own tinctures mostly for use as mouthwash but now you can buy the dried herb from me to either make your own tincture or just make a tea as needed to be used as a mouth or eye wash. Other uses of the herb include boosting the immune system and healing skin conditions. Please feel free to research this amazing plant yourself; there are many ongoing research studies.
