Diatomaceous earth taken in water daily for several weeks helped tighten receding gums. I think it is high in silica.

Dry, loose & thin skin may indicate Silica deficiency. Cabbage is one of many vegetables & fruits that contain Silica. Also, Diatomaceous Earth & Bamboo are other good sources of Silica.
Horsetail is often touted as being a good source, but the amount of silica in it is a lot lower & some get side-effects from it. Other herbs are good sources though, such as nettle & ground plantain (not the banana). Most green leaves & green vegetables contain silica.
Silica helps to maintain structural integrity. It is needed for collagen production, so can support many different areas of the body - the hair, skin, nails, bones & heart especially may benefit from extra Silica in the diet.
