Absolutely yes. I drink herbal teas and I'm quite sure they help me. They also give me something safe to drink, as I cannot have coffee or fizzy drink or even milk.

But for me, I had to change my diet before I was able to benefit properly from additional nutrients and detoxes.

Cleaned up the diet and then the benefits started. Detox was still not easy, but the pathways were more open and I had a better gut/liver condition to deal to the job, rather than a toxic and overburdened gut and liver unable to cope with increased movement of toxins. So they basically got shifted around a body that was too ill to eliminate properly.

That's my experience. I really believe the benefits of excluding the bad foods and encouraging an increase in good cannot be over emphasised! There are plenty of healthy alternatives to sugar and gluten/yeast products out there. And plenty of alternatives to coffee, fizzy drinks and milkshakes by the many detox herbal teas out there that JK has pointed out.
