Cocoons may be tough or soft, opaque or translucent, solid or meshlike, of various colors, or composed of multiple layers, depending on the type of insect larva producing it. Many moth caterpillars shed the larval hairs ( setae ) and incorporate them into the cocoon; if these are urticating hairs then the cocoon is also irritating to the touch. Some larvae attach small twigs, fecal pellets or pieces of vegetation to the outside of their cocoon in an attempt to disguise it from predators. Others spin their cocoon in a concealed location—on the underside of a leaf , in a crevice , down near the base of a tree trunk , suspended from a twig or concealed in the leaf litter . 
Every woman is unique, so the amount and form of saw palmetto you need won't be the same as for someone else.
As a general guideline, a common dose for men is 320 mg. of extract per day, standardized to at least 85-95% fatty acids with a guaranteed minimum of -% sterols. ("Standardized" means you get the same amount of active ingredients every time). You may decide to start with a somewhat lower dose.
In men, it can be taken for six weeks before any effect is noticed. If improvement is noted, it is recommended that men take it continuously. Since you're trying to reduce DHT like the men are, you could do the same.
As you can imagine, a supplement program can get complicated. Therefore, we recommend you seek guidance from a naturopathic doctor or other qualified health professional.
WARNING: The quality of botanical supplements varies widely. Don't buy any herbal or botanical product unless it has a "standardized" amount of the active component listed on the label. A "standardized" product has a consistent amount of active ingredients from one bottle to the next. If you buy a product that is not standardized, you have no clue as to what you are actually getting and may be wasting your money.
