For mild to moderate skin conditions a healthy diet and lifestyle is routinely recommended. This can certainly help but if there is a more fundamental cause to the skin condition, for example a genetic disposition or latent infection, this alone will not solve the problem. Often, creams containing benzoyl peroxide and salicylic acid are suggested and both can lead to dry, irritated and prematurely aged skin. Many such topical products, including the retinoic acid based products, cause skin irritation and sensitivity to the sun. The common denominator for these products is that they all treat the end result of metabolic problems in the skin but do little to correct these processes with ingredients that stimulate the immune system and healing processes. Sausage Tree Cream is unique in that it targets the metabolic processes that cause skin conditions providing longer lasting results. And given its careful formulation it can be used in conjunction with other topical agents.
Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more  or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram.  [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography .  : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity.
