The fluid medium suspending red and white blood cells, serum has one narrow job: keeping those cells nourished to move oxygen inward and carbon dioxide outward. Every other function the bloodstream performs in a toxic body is compensatory overflow.
Blood serum is the fluid component of the bloodstream that carries the red and white blood cells. In Aajonus's framework, the serum is the medium in which the cellular elements of the blood are suspended and through which they move, and it plays a specific supporting role that is distinct from the work of the cells themselves. The serum feeds the red and white blood cells, keeping them nourished so they can perform their two designated tasks: delivering oxygen to every cell in the body and removing carbon dioxide from the body. Beyond that supporting function, the serum is not described as a primary delivery vehicle for nutrients to other tissues. That job belongs to the lymphatic system.
Aajonus was pointed in correcting the conventional framing of blood as the body's general nutrient transport system. He held that the blood, including its serum, was designed to do something far narrower and that all the additional work the bloodstream performs in a toxic, modern body is overflow work it was never built to handle. The lymphatic system was supposed to feed every cell in the body except red and white blood cells. When the lymphatic system becomes congested, which Aajonus attributed primarily to the consumption of hydrogenated and cooked vegetable oils, the bloodstream and its serum are pressed into service as a feeding and detoxification vehicle, work that taxes the system enormously and reduces its capacity to manage oxygen and carbon dioxide efficiently.
What Serum Is And Does
The serum is the fluid portion of the blood in which red and white blood cells are suspended and transported. Aajonus described it plainly: "we have the serum that feeds the red and white blood cells." Its primary orientation is toward maintaining the viability of the cellular elements of the blood, not delivering nutrients broadly throughout the body.
The serum circulates within the bloodstream alongside the red cells, the white cells, enzymes, vitamins, and phagocytes, which Aajonus described as fatty cells that eat things. The entire bloodstream, serum included, was designed in his view for a simple two-part function: oxygen delivery inward, carbon dioxide removal outward. Everything else the blood does in a toxic human being is compensatory.
The Serum and Sterility
One of Aajonus's more pointed observations about blood serum concerned the medical profession's characterization of it as sterile. He stated directly that the blood serum is "relatively sterile," meaning that it does not harbor the same level of bacterial activity found in other parts of the body. He acknowledged that there is some bacterial presence in the blood, with bacteria consuming waste and discarding their own waste into the kidneys for elimination. But compared to the red and white blood cells themselves, which he said have a very high bacterial nature, the serum has low bacterial activity.
He then rejected the concept of true sterility as a meaningful or honest category: "It is really not sterile but the medical profession loves to use the word sterile and get you to believe that part of your body is truly sterile and it is not. Because they say sterile is safe and clean." His position was that sterility is a medical rhetorical device rather than an accurate biological description, and that even the relatively low-bacteria serum is not a genuinely sterile environment.
The Serum and the Kidneys
The relationship between blood serum and the kidneys is one of the more detailed areas Aajonus addressed. The kidneys filter water out of the blood serum so that the body can regulate blood thickness and temperature. When the body gets cold, the kidney throws off more H2O to thicken the blood and help the body stay warm. When the body is hot, the kidney does not release fluid as readily, in order to keep the blood thinner and the system cooler.
The central mechanical problem that kidney filtration creates is the risk of losing red and white blood cells along with the serum and its water content every time urination occurs. Aajonus explained that the kidney solves this problem by producing ammonia. Ammonia functions like a negative magnet: "When your kidney produces the ammonia, the red and white blood cells are repulsed from going into the kidney." This prevents the loss of red blood cells through urination, which would otherwise produce a constant low-grade anemia every time the body needed to regulate its fluid levels.
He clarified that while this ammonia mechanism strongly protects red blood cells, it is somewhat less complete in its retention of white blood cells. Aajonus stated that the kidney reserves roughly half to seventy percent of white blood cells in the process, meaning a significant portion of white blood cells do pass through and are excreted in the urine. He noted: "Massive amount of white blood cells, fatty cells, white blood fatty cells will be found in the urine. So its main purpose is to stop the loss of red blood cells. However, it does reserve half to 70% of the white blood cells in doing so."
The ammonia itself is only problematic in very concentrated amounts. In the quantities produced for this filtering function, it is not toxic and is simply passed out with the urine. This is Aajonus's framework explanation for the presence of ammonia in urine as a byproduct of the kidney's separation of blood cells from the serum.
He also connected this mechanism to a description of what healthy animal urine contains as a result of this process. He noted in one newsletter passage that "kidneys produce ammonia to separate red and white blood cells from blood serum so we do not become anemic whenever we urinate," and that in healthy animals such as cows revered in India, urine is rich in proteins, fats, vitamins, minerals, and enzymes because those substances pass through with the serum even as the cells are held back.
The Serum and the Spleen
The spleen's interactions with the blood are closely connected to the serum's function as the carrying medium for red cells. When the spleen dumps stored red blood cells back into the bloodstream following blood loss or cold temperatures, those cells are released into the serum, thickening the blood. Aajonus described this process in consistent terms across multiple workshop contexts: "the spleen will dump a lot of red blood cells into the blood serum. The blood gets thick. It gets hotter."
When the body is too hot, the reverse process occurs, and the spleen draws red blood cells out of the serum, thinning the blood and helping the body cool. A temperature change of 1.5 to 2.5 degrees triggers a measurable change in red blood cell quantity within the serum, according to Aajonus.
The serum is the environment into which these regulatory adjustments are made. Without a healthy serum carrying the cells properly, the spleen's ability to modulate temperature and compensate for blood loss would be compromised.
Serum Versus Lymphatic and Neurological Fluids
Aajonus consistently described three fluid systems in the body, and he was precise about distinguishing them. Blood serum is thicker than neurological fluid. The neurological fluid he described as "very thin solutions but full of heavy metallic minerals." The bloodstream, including its serum, is "much thicker." The lymphatic fluid he described as "a very thick, slow-moving system" that is "predominantly fat" and that appears "milky" near the intestinal tracts where fat is being absorbed, becoming "almost translucent" but still cloudy as it is further digested and distributed.
These distinctions matter in his framework because each fluid system has a specific job and each is degraded by different factors. The serum supports the blood cells. The lymph feeds all other cells and removes waste. The neurological fluid conducts light and electricity for communication. Confusing their roles or placing burdens meant for one onto another is, in Aajonus's view, how chronic disease and energy depletion develop.
Water in the Blood Serum
Aajonus addressed the question of water in the blood serum in the context of a critique of Dr. Batmanghelidj's claims about water. He stated that water "circulates in the blood serum but very little is absorbed cellularly, causing cellular dehydration and bodily swelling." His position was that water moving through the serum does not translate into proper cellular hydration because cells cannot absorb free H2O. Only water that is nutrient-bound in food, particularly in raw foods like raw meat, milk, and fruit, can be fully absorbed cellularly.
This is why Aajonus repeatedly pointed to the water content of raw foods as sufficient for hydration. Raw meat is 45 to 55 percent water. Raw milk is 82 percent water. Raw fruits are 86 to 92 percent water. He stated that drinking plain water thins the blood serum and creates problems: "If I drink too much fluid, the blood gets too thin and I get too cold." He noted that all fluids thin the blood to some degree but that plain water does it the worst.
The serum itself requires a certain thickness to function well, and that thickness comes from having the appropriate concentration of red blood cells and the appropriate nutrient density in the fluid itself. Excessive plain water consumption dilutes the serum and disrupts that balance.
What Damages the Serum Environment
Because the serum is the medium in which the blood cells operate, anything that damages the red or white blood cells or disrupts their reproduction ultimately degrades the functional quality of the serum environment. Toxic bone marrow is the most significant upstream cause Aajonus cited. When bone marrow is contaminated with heavy metals such as aluminum and tin, the red and white blood cells that mature there are weak, and weak cells entering the serum cannot perform their jobs adequately. He estimated that bone marrow toxicity in many people reduces blood function by 20 to 30 percent on average.
Salt was another specific damaging agent he named. He described the mechanism by which even very small amounts of salt cause red blood cells to clump and die: "Two little bitty grains create enough clumping to destroy two million red blood cells." When those cells die within the serum, the body must replace them, which takes bone marrow resources. If a person is consuming salt regularly with every meal, the ongoing destruction of red blood cells taxes the bone marrow continuously and deteriorates the system over time.
Cooked foods entering the bloodstream were also named as a source of serum burden. Aajonus described leukocytosis as a measurable consequence: eating a cooked meal causes white blood cell counts to drop, because the white cells are mobilized to deal with the toxic particles that have entered the bloodstream through a compromised lymphatic and digestive system. When white blood cells are consumed defending the serum against dietary toxins, they are not available to remove carbon dioxide from tissues, which results in lactic acid accumulation in muscles and reduced energy.
The Serum and Thyroxine
In one specific clinical observation, Aajonus described monitoring thyroxine levels in blood serum as a research practice. He stated that he took quarter-teaspoon blood samples every minute from patients in whom the heart had stopped and breathing had ceased, then had those samples analyzed for thyroxine levels in the serum. He found that thyroxine in the serum doubled every minute during those conditions, and that by the fourth or fifth minute the thyroxine appeared to be functioning at very high levels. His point was that thyroxine measurements in blood serum under normal circumstances do not reflect actual glandular activity or deficiency in any meaningful way, because the body's hormonal output changes dramatically depending on its moment-to-moment condition.
He applied this observation to his broader critique of thyroid testing and thyroid medication: you should not have significant levels of glandular hormones such as thyroxine in the blood serum when the body is calm and healthy, because endocrine glands are for emergency purposes only. Finding low thyroxine in the serum under standard testing conditions does not indicate a deficiency requiring pharmaceutical supplementation. It may simply indicate that the body is not in an emergency state at the time of the blood draw.
