Very effective. Tanggal ang hyper acidity ko. On my 2nd canister now. Ang bango din nito at ang sarap. Refreshing, mild and calming. I love that I can drink it anytime of the day kasi caffeine free sya. I even bought 2 Muji teapots for my Ninma teas! Nakakainspire na may gantong brans na pinagiisipang maige at natural ang products. More power po!
