{"type":"firestarter.listing","listing":{"id":"lst_hHBPExVM","product_name":"Muscle Ease","category":"Herbal Tea","description":"A tart hibiscus and lemongrass blend with earthy kava root.\nFour botanicals in one cup. Hibiscus and lemongrass lead: tart, citrusy, cranberry-bright. Kava root brings a deep, earthy, peppery base, and white willow bark rounds it with a woody bitterness underneath. The result tastes like a cranberry-lemonade with an herbal bite, and a mild tingle on the tongue from the kava.\n\nThe cup for winding down.\nThis is a blend to reach for at the end of a long day or after hard physical effort, when you want to slow down and sit with something warm and tart. Brew it hot and sip slowly, or pour it over ice. The ritual is the point: the warmth, the pause, the tart cup in hand.\n\nHow to use it.\nSteep 1.5 teaspoons in 8 ounces of full-boil water for 7 minutes. Hot in cold weather, iced in summer. The longer steep draws out the full earthy character of the kava and willow. A mild numbing sensation on the tongue is normal and expected with quality kava. Blended in our Salem, Oregon kitchen.","images":["https://cdn.shopify.com/s/files/1/0806/0862/4962/files/muscle-ease-loose-tea-ybtco.webp?v=1779851320","https://cdn.shopify.com/s/files/1/0806/0862/4962/files/muscle-ease-brewed-tea-ybtco.webp?v=1779851318","https://cdn.shopify.com/s/files/1/0806/0862/4962/files/muscle-ease-tin-tea-ybtco.webp?v=1779851316"],"price":18,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:17.029Z"},"share_url":"https://firestarter.network/l/lst_hHBPExVM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
