Abstract: A method for protecting muscles, comprising administering to a subject in need an effective amount of a FU-LING (Poria cocos) extract, tumulosic acid and/or a pharmaceutical acceptable salt of tumulosic acid. In particular, the method of the present invention is for protecting muscle cells against injury, promoting regeneration and repair of muscle, regulating, treating and/or delaying muscle atrophy (especially caused by aging, diseases, and cachexia), or helping normal muscle contraction, maintaining normal muscle physiology, maintaining normal neuromuscular function, maintaining normal energy metabolism, or enhancing energy level.

Abstract: A method for regulating, preventing, and/or treating pulmonary injury, and/or for regulating, preventing, and/or treating pulmonary injury-related diseases is provided. The method comprises administering to a subject in need an effective amount of FU-LING extract, tumulosic acid, dehydrotumulosic acid, dehydrotrametenolic acid, and/or poricoic acid A.

Abstract: Use of Cistanche tubulosa extract, isoacteoside and/or a pharmaceutical acceptable salt of isoacteoside in the manufacture of a medicament or a food product for protecting muscles, wherein the medicament is particularly used for protecting muscle cells against injury to regulate, treat and/or delay muscle loss, and especially for the muscle loss caused by aging, diseases, and/or cochexia. The food product is a health food, a nutritional supplement food, or a special nutrition food.
