To begin with I put 1/2 bunch of cilantro in my normal morning smoothie made with frozen banana and blueberry pieces, almond milk, probiotic plain yogurt, a raw egg plus a low dose of collagen power (I learned a full dose of bovine collagen gave me a stomach ache, too much fiber). I tried for months to accept the taste of cilantro in the smoothie, thinking I could train myself to like it. I gave up putting in in because it ruined my delicious smoothie taste. So I'd make my tastely smoothie, empty out the blender and blend up 1/2 bunch of cilantro with 1/2 cup of water and chug that down like a tonic.
Frozen cilantro worked just as well. Initially I tried cilantro oil tablet but didn't get any relief.
