Re: sometimes bitter, sometimes sweet?

That’s okay when your tongue is white. It helps only very slightly, though and not at all in other conditions. I do not like brushing the tongue coz the endings on the papillae are extremely delicate and can be destroyed. When I brush my tongue at all, I’d do it very very lightly and using a very soft brush. It is, afterall, one’s own health that determines on how effective the taste buds work. On that note, overdose of wine and spicy food adversely affects your senses in tasting very fine tastes such as that of tea. Smoking and strong liquor are the worst enemies in taste. If you notice, those people or even chefs who drink and smoke a lot prefer food with much stronger tastes.
