Jg, that happens often when you mix crushed garlic with lemon. Especially if you don't consume it within a few hours. It's some chemical reaction.
It doesn't affect the taste, and probably not the medicinal properties, it's just quite unappetizing!!

Mixture can turn green or light brown, no harm, depends on the ingredients mainly ginger and garlic. It is important that you use clay/earthen pot or procelin as mixture can react with metal as it is ascetic acid. ACV must be organic, raw and unfiltered for best result. Honey must also be raw and pure.
