Potassium sulfate is a high content and quick acting potassium fertilizer, mainly prepared from sulfate ore anhydrous potassium magnesium aluminate and potassium chloride as raw materials. It is a white or light yellow crystalline particle with two crystal forms, α - and β -. The α - type is a colorless crystal in the hexagonal crystal system, while the β - type is a colorless crystal in the orthorhombic crystal system. It has a bitter and salty taste.

Generally, it contains 90% to 95% potassium sulfate, 50% to 52% potassium (K2O), 16% sulfur (S), and less than 2.2% chlorine (Cl); In addition, there are small amounts of sodium (Na), calcium (Ca), magnesium (Mg), bromine (Br), etc., which are insoluble in ethanol, acetone, and carbon disulfide, but easily soluble in water and can be directly absorbed and utilized by plants. They can be used as base fertilizer, seed fertilizer, and topdressing. Experimental results have shown that the application of 1 kilogram of potassium sulfate can increase the yield of grain crops by 6-8 kilograms and sugar beets by 15.5-22.5 kilograms. Some chlorine sensitive crops (such as fruits, flax, tobacco, tea, citrus, potatoes, etc.) cannot be treated with potassium chloride, but can be treated with potassium sulfate.

Creatine monohydrate is an amino acid that is crucial for the production of adenosine triphosphate (ATP). Adenosine triphosphate is the main energy source for muscle contraction. It is a naturally occurring compound that exists in small amounts in meat and fish.

The main reason for supplementing creatine monohydrate is to saturate your intramuscular phosphocreatine storage and free creatine levels, which is not possible solely through diet. By supplementing creatine monohydrate, endurance athletes can increase ATP production and improve athletic performance. Creatine has significant benefits in increasing ATP production, as well as providing benefits beyond exercise performance. Supplementing with creatine also has potential benefits for brain health.

The issue of oxalic acid in wild vegetables does require a scientific approach.

universality
Most wild vegetables (such as purslane, dandelion, shepherd's purse, amaranth, etc.) contain oxalic acid, but the content varies greatly. For example:

High oxalic acid: amaranth (about 300-500mg/100g), purslane

Low to moderate oxalic acid: shepherd's purse, dandelion tender leaves

Risk points
Oxalic acid easily combines with calcium to form calcium oxalate (the main component of kidney stones), and long-term excessive intake may:

Affects calcium absorption

Increased risk of stones (especially in patients with urinary system diseases)

Niacin is a very important water-soluble vitamin that plays a role in many aspects of health, from brain function to heart health, and more.

Vitamin B3, also known as niacin and niacinamide, is an important water-soluble vitamin that alters lipids. It can be found in many common foods, including certain types of meat and offal, tuna, seeds, mushrooms, and more.

It is a part of the vitamin B complex, as well as other B vitamins including vitamin B1 (thiamine), vitamin B2 (riboflavin), etc.

Vitamin B3, commonly known as niacin, comes in three forms: niacin, niacinamide, and inositol hexanoic acid. Vitamin B3 niacin has been extensively studied and proven to be helpful in treating various common health problems.

So what are the uses of niacin, what are its effects on the body, and how does it affect your health? Vitamin B3 is an important vitamin for maintaining heart health and metabolism, and also helps balance cholesterol levels in the blood. In addition, it can help brain function, skin health, and even prevent or treat diabetes.

However, according to recent research, several well-known side effects of niacin may occur when taking high doses of drugs or supplements containing niacin. The most common side effects of niacin are headache, dizziness, and hypotension. Continue reading the complete list of uses of niacin, possible side effects, benefits, sources, and signs of deficiency.

Arbutin, also known as arbutin, arbutin, arbutin, arbutin or yangmei glycoside, originated from natural green plants and is a skin whitening active substance that combines the concepts of "green", "safe" and "efficient". Arbutin is an ideal whitening agent for whitening cosmetics, with two optical isomers, alpha and beta, and the beta isomer having biological activity. At room temperature, it is a white slightly yellowish powder that is easily soluble in water, methanol, ethanol, propylene glycol, and glycerol aqueous solutions. After dissolution, there is no precipitate, and it is insoluble in chloroform, ether, petroleum ether, etc.

It is added to many whitening and skincare products. Named after its discovery from the leaves of the bear fruit plant in the Rhododendron family, it was later found in the leaves of plants such as the Vaccinium genus in the Rhododendron family, the Pear genus in the Rosaceae family (such as the Western Pear and the Small Mountain Pear), and the Tiger Ear Grass genus in the Tiger Ear Grass family. After extraction, it is used as a medicinal and cosmetic additive.

Methyl salicylate is a colorless or yellow to red oily liquid with a unique herbal aroma, sweet and spicy in taste. It is an organic compound formed by the combination of the hydroxyl group of methanol and the carbonyl group of salicylic acid.

Methyl salicylate naturally exists in essential oils such as holly oil, ylang ylang ylang oil, and acacia oil, accompanied by a unique holly oil fragrance.

Effect and Function

Methyl salicylate is mainly used as an external topical red agent, commonly used for reducing swelling and relieving pain. However, due to its side effects such as affecting the activity of iron ions in the blood, it is now rarely used for oral medication. It has a local stimulating effect, which can promote local blood circulation. External application or local rubbing can produce skin vascular dilation, skin redness and other stimulating reactions, and reflexively affect the corresponding skin, muscles, nerves and joints, thereby reducing swelling, anti-inflammatory and analgesic effects, as well as relieving itching. Can be used for sprains, contusions, lower back pain, muscle pain, neuralgia, and itching relief.

Retinol is a fat soluble vitamin that exists in the form of free aldehydes or esters in animal food. It is abundant in fat, protein, dairy, and liver. Plants do not contain vitamin A, but its precursor (provitaminA) is present in vegetables such as carrots and tomatoes. After being absorbed by animals, it can be converted into vitamin A. Retinol is essential for maintaining the stability of human growth, development, reproduction, and cell membranes, and plays an important role in the visual process. Retinal is constantly metabolized and consumed in the body, and needs to be supplemented in a timely manner through the oxidation of vitamin A.

Vitamin A is related to the normal structure and function of upper and lower cells. Deficiency can lead to dryness, inflammation, and even blindness of the conjunctiva and cornea, as well as damage to the respiratory epithelium, making it prone to respiratory infections, hair loss, and delayed infant development. Vitamin A oil, as a nutritional supplement, is a fatty oil or its concentrate obtained from the liver and pylorus of aquatic animals.

Crush fresh fish liver and pylorus, add 1-2% sodium hydroxide solution to pH 8-9. Retinol can be used in sausages, margarine, bread, dairy products, fruit juice powder, peanut butter, etc.

Although edible glucose and industrial glucose have the same chemical composition (both are C ₆ H ₁ ₂ O ₆), they have essential differences in raw materials, purity, hygiene standards, and uses. Edible glucose is made from food grade raw materials (such as corn starch), which have undergone strict refining and sterilization treatment, with a purity of ≥ 99.5%, in compliance with food safety standards (such as GB/T 20880), and is used in food, medicine, and health products; Industrial glucose may contain harmful impurities such as heavy metals and sulfides, with low purity (70%~95%), and is only used in sewage treatment, chemical or construction fields. It is absolutely inedible and misuse may lead to poisoning or health risks. The two have similar appearances and need to be distinguished by packaging labeling (such as SC license) or testing reports.

Sodium nitrite (NaNO ₂) is a common food additive mainly used for marinating meat (such as ham, sausages, bacon, etc.), which has preservative, color preserving, and flavor enhancing effects. However, excessive intake or improper use may pose health hazards, mainly including the following aspects:

1. Acute poisoning (high-risk)
Toxic dose: Adults may be poisoned if ingested 0.2-0.5 grams, and may die if ingested 1-2 grams.

Symptoms: Dizziness, vomiting, difficulty breathing, decreased blood pressure, and in severe cases, tissue hypoxia, coma, and even death due to methemoglobinemia.

Vulnerable population: Children or those who accidentally consume salt are at higher risk (such as mistakenly using it as salt).

2. Carcinogenic risk (long-term exposure)
The formation of nitrosamines: Nitrites react with amines produced by protein decomposition under gastric acid or high temperature cooking conditions, producing strong carcinogens such as nitrosamines (N-nitroso compounds).

Related cancers: Long term excessive intake may increase the risk of gastric cancer, esophageal cancer, colorectal cancer, and other cancers.
