The meridians of the Kidney channel connect to the Lung and are tied to the root of the tongue (Shéběn), circulating Qi and Blood, connecting Yin and Yang, and running internally to warm the Marrow. If congenital essence is insufficient, Kidney Water fails to ascend to nourish Heart Yang and unblock Lung Qi. The Classics state: "The Lung governs sound, and the Heart governs speech." The tongue is the sprout of the Heart; when the Heart and Lung are disharmonious, causing stiffness at the root of the tongue, one cannot produce speech. Treatment should focus on nourishing the Kidney, benefiting the Lung, and draining Heart Fire, so that Water ascends and Fire descends, Yin and Yang become harmonious and smooth, and speech naturally becomes clear.
Shenqi Wan (Kidney Qi Pill) is indicated for delayed speech; this formula is the primary treatment.

Grind these in equal proportions into powder. Mash Tianmendong and Maidong, mix with honey to form pills, and coat with 3 qian of Cinnabar (Zhusha). Take each dose with Decoction of Juncus Effusus (Dengxincao), taken two or three times daily.
(Attachment: Spasm of Hands and Feet)
The Kidney governs bones, and the Liver governs sinews. Bones become firm and strong when nourished by marrow; sinews flow smoothly when nourished by blood. Children with weak legs and delayed walking also suffer from insufficient congenital essence. It is advisable to use herbs that nourish Kidney Water, benefit Liver Qi, nourish blood, and tonify the Spleen. Why worry about inability to walk? Alternate taking Qipi Wan (Spleen-Initiating Pill) and Dihuang Wan (Rehmannia Pill).
