Silica will complete the cycle of those born between November 23 and December 21. A lack of this mineral will cause dull hair, weak nails, and poor skin. Complaints from the lack of this mineral are neuritis of the lower limbs, goiter, rheumatism, overheated blood, and feverishness. Silica can be obtained by eating the skins of all fruits and vegetables, figs, prunes, and strawberries; or in the New Body Herbal Formula SAG (Sagittarius).
