Symbiogenesis, or endosymbiotic theory, is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes.It states that several key organelles of eukaryotes originated as a symbiosis between separate single-celled organisms.olecular and biochemical evidence suggest that mitochondria developed from proteobacteria (in particular, Rickettsiales, the SAR11 clade, or close relatives) and chloroplasts from cyanobacteria (in particular, nitrogen-fixing filamentous cyanobacteria).
Standard ratios are:Tinctures of dried, intense botanicals are 1:10. This means 1 part herb, an ounce for instance, to 10 parts liquid, also measured in ounces. Examples of this type of herb are cayenne and the resins such as myrrh and propolis.
A tincture can be made of a single herb or a combination of herbs. Herbal tinctures are used because of their fast absorption and because of their long-shelf life. If the alcohol content of a tincture is a concern, glycerin extracts, capsules, or tablets may be used instead. Herbal tinctures are sold in health-food stores, some drug and grocery stores, and online. Some tinctures, such as arnica and compound tincture of benzoin, should only be used externally.
