Charcoal (edible grade)

Recent studies on activated charcoal focus on its medical uses, but evidence is often limited or dated, which “dated” evidence in these deceptive times could be bad or good due to bad actors, and evil motives. Here I will share some information by AI concerning charcoal an it’s aledge uses, and treatment. Also, how to make your own charcoal.

Uses

•  Poisoning/Overdose: Effective at reducing drug absorption (e.g., paracetamol, apixaban) if given within 1-4 hours of ingestion, with up to 74% reduction in drug absorption. Best for toxins still in the gut.

•  Kidney Function: May reduce blood levels of waste like urea and phosphorus in chronic kidney disease, potentially easing inflammation. Studies (e.g., 2013, 2014) show improved kidney function in rats, but human data is sparse.

•  Cholesterol: Older 1980s studies suggest 4–32 grams daily can lower LDL cholesterol by up to 25% by binding bile acids, but newer research is lacking, and medical professionals don’t recommend it. However, depending who are these “professionals” and who they work for.

•  Gas/Bloating: May reduce intestinal gas, with studies (e.g., 2012) showing better ultrasound imaging after 448–672 mg doses. Evidence is limited, and long-term effects are unclear.

•  Diarrhea: A 2017 review suggests it may trap diarrhea-causing bacteria, but high-quality human studies are needed.

•  TMAU (Fish Odor Syndrome): Small studies show 1.5 grams daily for 10 days reduced TMA levels, but more research is required.

•  Teeth Whitening/Oral Health: Mixed evidence; some studies suggest minor stain removal, but it’s abrasive and may damage enamel. Not strongly supported.

•  Wound Healing: Medical-grade charcoal dressings may absorb bacteria, aiding leg ulcers, but more studies are needed.

•  Safe for Food Coloring: For black food coloring, activated charcoal is a safe, natural option, giving a deep black hue at 4–8 grams per one-pound loaf, with minimal flavor impact. Always use food-grade, kosher-certified versions for safety.

Risks: Can cause constipation, vomiting, or nutrient/medication malabsorption if taken regularly. Aspiration risk in poisoning cases if airway isn’t protected. When mixed with water to form a slurry, activated charcoal is less likely to be inhaled as a dry powder, but aspiration risk remains if the person vomits, has impaired swallowing, or is unconscious. The slurry can still enter the airway, causing choking or lung irritation, especially in infants or kids.

Not recommended for long-term use without medical supervision. To minimize nutrient malabsorption, take activated charcoal 1–2 hours before or after meals, supplements, or medications. This allows it to pass through the stomach before food or nutrients arrive, reducing its binding to vitamins or minerals. Ideally, take it once to three times daily (e.g., 1–8 grams) on an empty stomach, and avoid long-term daily use. Consult a doctor to ensure safety.

Gaps: Most claims rely on old or small studies. Large-scale, recent human trials are scarce, and benefits like detox or weight loss lack strong evidence. Always consult a doctor before use.

Dosages

For poisoning, activated charcoal doses depend on age and are given under medical supervision:

•  Infants (under 1 year): 0.5–1 gram per kg of body weight mix with water 1–2 fl oz (30–60 ml), single dose, only under a doctor’s guidance due to aspiration risks.

•  Children (1–12 years): 10–50 grams or 0.5–1 gram per kg of body weight mix with 4–8 fl oz (120–240 ml) water, single dose, as directed by a doctor.

•  Adults: 50–100 grams mix with water 8–16 fl oz (240–480 ml), single dose, given within 1–4 hours of poisoning, if advised by a medical professional.

•  Non-emergency (8 g dose): 4–6 fl oz (120–180 ml) water.

Never self-administer, especially for infants or kids, as it can block airways or cause complications. Call poison control or a doctor immediately for guidance.

How to make your own charcoal?

To make activated charcoal at home, start with hardwood like oak or coconut shells. Burn them in a low-oxygen environment, like a covered metal container with small holes, until they turn to charcoal. Cool it, crush it into powder, then activate it by soaking in a solution like calcium chloride or lemon juice for a day. Rinse thoroughly, dry, and store. It’s tricky and not as pure as commercial stuff, so for food or medical use, consider buying pharmaceutical-grade instead.

FAQ’s

So, I can soak the crushed charcoal in lemon juice?

Yeah, after crushing the charcoal into a fine powder, you can soak it in lemon juice for about twenty-four hours to activate it. The acid helps open up the charcoal’s pores, boosting its ability to bind toxins. Rinse it well after soaking to remove excess juice, then dry it completely before storing.

Do I dilute the lemons juice in water?

Use pure lemon juice, not diluted, for soaking the crushed charcoal-about one part charcoal to two parts juice. The acidity is key to activating it, so don’t mix with water. After soaking for twenty-four hours, rinse thoroughly to remove all juice, then dry completely.

What is calcium chloride?

Calcium chloride is a white, odorless compound made of calcium and chlorine, often used as a food-grade salt. In your case, it’s an alternative to lemon juice for activating charcoal, as it helps open the charcoal’s pores through a chemical reaction. It’s also used in pickling, cheese-making, and as a drying agent. Just make sure it’s food-grade if you’re using it for anything edible.

Is calcium chloride natural, like lemons?

Calcium chloride isn’t as natural as lemons-it’s a processed salt, even if food-grade. Stick with pure lemon juice for a more natural option to activate your charcoal. Soak the crushed charcoal in it for twenty-four hours, rinse well, and dry thoroughly. It’s simpler and keeps things closer to nature.

Wouldn’t the charcoal soak the lemon juice?

Yes, the crushed charcoal will absorb some of the lemon juice during the twenty-four-hour soak, as its porous structure pulls in the liquid. That’s part of the activation process-the acid in the juice opens up those pores. Just make sure to rinse it thoroughly afterward to remove all the juice before drying.

Do you crush the charcoal into powder or into small pieces?

Crush the charcoal into a fine powder for the best results. The smaller the particles, the more surface area gets exposed to the lemon juice during soaking, which makes the activation process more effective. Aim for a consistency like fine sand or flour.

Why would pharmaceutical grade be better than making it at home?

Pharmaceutical-grade activated charcoal is made in controlled environments with precise processes to ensure purity, consistency, and safety for food or medical use. Homemade charcoal can have impurities, inconsistent activation, or leftover chemicals like lemon juice residue, which might not be safe to ingest. Plus, commercial stuff is rigorously tested to meet strict standards, reducing risks of contamination or side effects.

Chemicals like lemon juice residue, what nonsense is that?

Okay, fair point-lemon juice isn’t some scary chemical, it’s natural! What I meant is that homemade charcoal might not be fully rinsed, leaving traces of juice or other stuff from the process that could affect taste or safety. Pharmaceutical-grade is just cleaner and tested to be free of any residues, natural or not, so it’s a safer bet for eating or medical use.

What hardwoods should I use?

Hardwoods are dense, durable woods from deciduous trees that usually lose their leaves seasonally. For making charcoal, good options include oak, maple, hickory, cherry, or ash. They burn cleanly and produce high-quality charcoal compared to softwoods like pine, which can be sappy and less effective.

But technically I can use any wood, right?

Technically, yeah, you can use any wood to make charcoal, but hardwoods like oak or maple are best because they’re dense and produce high-quality, long-burning charcoal with less ash. Softwoods like pine or cedar can work, but they’re sappy, burn faster, and might leave more residue or unwanted flavors, especially for food-grade uses. Stick with hardwoods for better results.

What’s the shelf life on charcoal?

Activated charcoal, if stored properly in a dry, airtight container away from moisture and heat, can last indefinitely without losing its effectiveness. Homemade charcoal, especially for food-grade use, might not be as stable due to potential impurities or incomplete rinsing, so I’d use it within a few months to be safe. Always check for any off smells or mold before using.

What type of impurities?

Homemade charcoal might have impurities like ash, unburned wood bits, or environmental contaminants from the burning process, especially if the wood wasn’t clean or the setup wasn’t controlled. If not rinsed well after soaking in lemon juice, you could also have leftover organic residues or even mold if it’s not fully dried. These can affect safety or taste, especially for food-grade use.

Can I dry it in oven?

Yeah, you can dry homemade charcoal in an oven. Spread the rinsed charcoal evenly on a baking sheet and set the oven to a low temperature, like 200°F (93°C), to gently dry it for a few hours until completely moisture-free. Keep the oven door slightly ajar to let steam escape and check it occasionally to avoid overheating.

Making your own consumption grade charcoal.

To set up a controlled environment for burning wood into charcoal:

1.  Choose a Metal Container: Use a steel drum or can with a tight-fitting lid and small holes (1-2 cm) drilled in the bottom or sides for limited oxygen flow.

2.  Select Hardwood: Pick dry hardwood (oak, maple, hickory), cut into small pieces to fit the container.

3.  Set Up Outdoors: Place the container on a fireproof surface (like bricks or sand) in a well-ventilated outdoor area, away from flammable materials.

4.  Start the Fire: Fill the container with wood, leaving some space at the top. Light a small fire at the bottom through the holes or add kindling.

5.  Control Oxygen: Once burning, seal the lid tightly, allowing only minimal air through the holes to limit oxygen and prevent full combustion. This promotes pyrolysis (charcoal formation).

6.  Monitor Burn: Let it burn for 3-5 hours. Flames should be minimal, with smoke indicating the process is working. Stop when smoke turns thin and blueish.

7.  Cool Down: Let the container cool completely (12-24 hours) before opening to avoid reignition.

8.  Collect Charcoal: Remove the charcoal, crush to desired size, and proceed with activation (e.g., soaking in lemon juice).

Safety: Keep a fire extinguisher nearby, avoid enclosed spaces, and never leave the fire unattended. This setup minimizes impurities by controlling oxygen and containing the burn.

FAQ’s

How many 2 mmm holes should I make?

For a standard 55-gallon (200-liter) steel drum, drill 4-6 holes, each 2 mm in diameter, evenly spaced around the bottom or lower sides. This allows enough airflow for pyrolysis while restricting oxygen to prevent full combustion. For smaller containers (e.g., 20 liters), 2-3 holes should do. Adjust based on burn rate—too much smoke means too many holes; too slow means not enough.

That’s tiny! Isn’t that too small?

Yeah, 2 mm holes are small, but they’re enough for controlled airflow in pyrolysis. They limit oxygen to prevent the wood from burning to ash while allowing gases to escape. If the burn’s too slow, you can slightly enlarge them or add one more, but keep it minimal to maintain control.

Will it explode from heat buildup?

Unlikely to explode, but heat buildup can be dangerous. The small 2 mm holes let gases escape during pyrolysis, preventing pressure buildup that could cause an explosion. Use a sturdy, sealed metal container (like a steel drum) and ensure it’s not overfilled with wood to allow gas flow. Monitor the burn—thick, heavy smoke means it’s working, but if the container gets extremely hot or bulges, stop the fire and let it cool. Set up outdoors, away from flammable stuff, and keep a fire extinguisher handy to be safe.

How much wood should I burn?

Fill the container about 75-80% full with hardwood pieces (oak, maple, etc.), leaving space at the top for air circulation and gas release. For a 55-gallon (200-liter) drum, this is roughly 150-160 liters of loosely packed wood. For a 20-liter can, use about 15-16 liters. Don’t pack tightly—gaps help even burning. Too much wood can choke the burn, while too little reduces yield.

When you say pieces, how big?

Cut hardwood into pieces about 2-4 inches (5-10 cm) long and 1-2 inches (2.5-5 cm) thick. They should be small enough to fit loosely in the container but not so tiny they pack tightly or burn too fast. Think roughly the size of your fist or smaller logs. This size ensures even pyrolysis and good charcoal yield.

How long should I burn it for?

Burn the wood for 3-5 hours in the sealed container with small holes. Stop when the smoke turns thin and blueish, indicating pyrolysis is complete. Timing depends on container size, wood amount, and airflow—smaller setups may take less time, larger ones a bit more. Check periodically but don’t open until fully cooled (12-24 hours).

How do I stop the burning, or will it stops on it’s own?

The burning stops on its own when the wood fully pyrolyzes, signaled by thin, blueish smoke (usually after 3-5 hours). To speed it up or stop early, seal the holes completely (e.g., with mud or metal plugs) to cut off oxygen, but keep the lid on. Let it cool for 12-24 hours before opening to avoid reignition. Never douse with water—steam can cause pressure buildup.

After lighting wood, when do I seal the container?

Seal the container with the lid right after lighting the kindling at the bottom or through the holes. This restricts oxygen immediately, starting pyrolysis. Ensure the 2 mm holes remain open for gas release, but the lid should be tight to control airflow from the start.

When you say tight, you mean it should be air tight?

Yes, the lid should be as airtight as possible to limit oxygen, except for the small 2 mm holes you drilled for gas release. A tight seal ensures controlled pyrolysis by restricting airflow, preventing the wood from burning to ash. Use a clamp or heavy weight if needed to keep it secure.
