I have put dried marshmallow root in a jar with cold water overnight, then drank it the next day and put more water in with the same roots. It keeps producing mucilage, but how long is it safe to keep doing this? I live in a very dry climate and feel like it helps with keeping the mucous membranes from drying out.
Following to see what others say. I have kind of the same deal as you – but I would worry more about mold than the lack of mucilage – but hopefully others will chime in here.
