Serenoa repens
Also known as Sabal palm, Sabal, Serenoa, Jacks, Serenoa or saw palmetto, Sabal serrulata.
Saw Palmetto is a nerve sedative, expectorant, and a nutritive tonic, acting kindly upon the digestive tract and tending to improve the appetite, digestion, and assimilation. Its most direct action appears to be upon the reproductive organs when undergoing waste of tissue; in some nutritional way it is asserted to enlarge the breasts, ovaries, and testicles, while the paradoxical claim is also made that it reduces hypertrophy of the prostate.

Action and Therapy. Saw Palmetto is a nerve sedative, expectorant, and a nutritive tonic, acting kindly upon the digestive tract and tending to improve the appetite, digestion, and assimilation. Its most direct action appears to be upon the reproductive organs when undergoing waste of tissue; in some nutritional way it is asserted to enlarge the breasts, ovaries, and testicles, while the paradoxical claim is also made that it reduces hypertrophy of the prostate.
Therapy. It is a sedative to all irritable conditions of these organs, and is a profound nutritive tonic, operating much like phosphorus. It increases the size and secreting power of the mammary glands where they are abnormally small and inactive.
Physiological Action. The attention of the profession was called to this palm by Goss and others, from its superior fat producing properties in animals. It was observed as soon as the berries matured that the animals which fed upon them grew very sleek and fat.
Specific Indications. Relaxation with copious catarrhal secretion; lark of development or wasting of testicles, ovaries, or mammae; prostatic irritation with painful micturition, and dribbling of urine, especially in the aged; tenderness in the glands and other parts of the reproductive organs.
