Two very important factors in human life—which play vital roles in promoting well being—includes returning the body to homeostasis and giving boost to body called lifeforce to get overall health free from diseases, i.e., its optimal balanced functioning ability. When the body is at homeostasis, there is no place for disease. It is only when the body is out of balance (something is deficient, in excess or stagnating) that pain, illness or disease can occur. The application described is based on returning the body to homeostasis (removing the problem and balancing the body) by providing lifeforce and not on dealing with the symptom (e.g., pain, vitamin deficiency). Imbalance results in various diseases and adverse health conditions (starting from aging to diabetes and cancers). This wonderful composition will interact with the body in a way that allows it to boost lifeforce and reach homeostasis no matter which direction it was. In this combination, in the form of liquid, all the 14 ingredients (Lepidium meyenii (Maca), Croton planstigma (Dragon's blood) tree sap, Uncaria tomentosa (Cat's Claw), Morinda citrifolia (Noni fruit) 4:1 PE, Lutein, Lycopene 5%, Flaxseed Oil (Omega-3-Fatty Acids), Vinpocetine, Phosphatidyl Serine 50%, Korean Ginseng 80%, Bacopa monnieri (Bacopin), CDP Choline (Cognizing), Guaranine (Guarana Seed PE 12%), Yerba Mate Ext. 8%) work as mixture for returning the body to homeostasis and give it lifeforce.

Chimeric proteins comprising soluble Tissue Factor (sTF) and another subunit (e.g., annexin V) are described.
