Treats the tissue states of atrophy and excitation *Meridians*: Kidney, Bladder, Liver, Spleen
 
Felter: Specific Indications: relaxation with copious catarral secretions; lack of development or wasting of testicles, ovaries, or mamae; prostatic irritation withpaonful micturition, and dribbling of urine, especially in the aged; tenderness in the lands and other parts of the reproductive organs.
 
Fyfe: From the fact of its being a general tonic, saw palmetto may be hopefully prescribed in any depraved condition.  Its special tonic and expectorant action on the respiratory mucous membrane makes it a valuable remedy in phthisis, in tuberculosis, laryngitis in acute and chronic laryngitis, in bronchitis, in asthma, in whooping-cough, and in cough generally when due to irritation of the respiratory mucous membrane.  It is also highly recommended as a special remedy in catarrh-both in acute and chronic.  In these cases and inhalation of the vapour of say palmetto is beneficial and not unpleasant.
 
Ellington: wrote that 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.  Read noticed the healthfullness of the animals that fed upon them..Found to improve digestion, increase the flesh, strength and weight, and steadily relieve irritation of mucous structures, especially those of the nose and air passages...it is a tonic in stimulating the nutrition of the nerve centres. Ellington talks a lot about Saw Palmetto being a profound nutritive tonic. …increasing the size and secreting power of the mammary gland...but only indicated when they are abnormally small and inactive. (so no artificial GnRH effect)  "It may be given with confidence in wasting of the testes in the early stages and Ellington had retarded the development of varicoceles in the testes…-"this agent is ascribed considerable power in reducing the size of hypertrophied prostate in old men, and in quickly relieving cystic and other disorders incident to this condition.  Also..BIG HELP in correcting the irritable character of the urine, increases the muscular power of the patient to expel the urine and produce a sense of relief, that "is in every way gratifying and satisfactory"!!!!  Ellington said that it is credited with cures in the treatment of aphonia.
 
Lyle: excellent expectorant; it soothes the mucous membranes, to treat the common cold, acute and chronic laryngitis and bronchitis.
 
Dr. Hale: considered it to be one of the most effectual uterine remedies.  He found it to be the chief remedy in metritis, pelvic cellulitis, peritonitis, salpingitis, ovaritis, appendicitis, perityphlitis and proctits, especially if the prostate gland is involved. So the berry contains a steriod type chemical sistosterol that seems to aid this Kd yang-Sp qi deficiency restoring effect of the herb.  (this compound seems to be what inhibits the effects of dihydrotestosterone on the prostate gland.)
 
Peter Holmes: recommends the combination of Saw Palmetto with Marigold and Echinacea for inflammatory conditions of the reproductive organs.  *David Winston* combines Nettle Root (Urtica dioica), Collinsonia (Collonsonia canadensis) and White Sage (Salvia Apiana) in treating Benign Hypertrophic Prostates.
 
Matt Wood: It improves nutrition and assimilation and rebuilds the adrenocortical base, which calms down nervousness.  By decreasing atrophy and dryness it also decreases heat and irritation.  It has been known to increase the size of breasts, testicles and reproductive organs when there was malnutrition. However, its effect on the prostate is to reduce swelling and irritation. It is part of the Fountain of Youth in Florida!
 
Jeremy Ross: Serenoa appears to have a normalizing function, enlarging urogenital organs b tonic action when atrophied and reducing them by anti-inflammatory action when pathologically enlarged.
 
BPH: urinary antiseptic and diuretic for cystitis; urogenital catarrh, prostatic hypertrophy; anabolic agent and endocrine agent for general debility, sex hormone disorders, testicular atrophy *Recent Research*: There is a great deal of research associated with prostatic disease.  The results suggest that SPE may have potential application value for the prevention or treatment of erectile dysfunction through an increase in iNOS mRNA expression and inhibition of PDE5 activity in corpus cavernosum smooth muscles.  It has an inhibitory effect on cell growth that is associated to the down-regulation of inflammatory-related genes and to the activation of NF-kappaB pathway in prostate tissue.(anti-cancer effect) Serenoa repens could lead to an improvement of androgenetic alopecia. This report suggests that saw palmetto extracts selectively affect the adipocyte differentiation
