April 20 is World Gout Day, also known as National Gout Awareness Day. The date is chosen because 420 μmol/L is the critical threshold for diagnosing hyperuricemia, the key pathological basis of gout. Many people ignore high uric acid because there are no obvious symptoms in the early stage. However, long‑term hyperuricemia acts as a silent killer, quietly damaging kidneys, blood vessels, pancreatic islet function, liver and other organs without obvious discomfort. Today, we will decode what your body is telling you through uric acid levels, and introduce how natural plant extracts can assist in maintaining uric acid balance.

 

What Is Uric Acid & Why Does It Rise?

Uric acid is the final waste product of purine metabolism in the human body. It comes from two sources: endogenous production accounts for about 80%, generated by normal cell metabolism and related to genetics and physical fitness; exogenous intake accounts for about 20%, mainly from high‑purine foods such as animal offal, seafood, and concentrated broth. Under normal circumstances, uric acid production and excretion (mainly through kidneys and intestines) maintain a dynamic balance. Once this balance is broken, excessive uric acid production or impaired excretion will lead to elevated blood uric acid levels.

Clinically, hyperuricemia can be diagnosed when two fasting blood uric acid tests on different days both exceed 420 μmol/L. When blood uric acid exceeds the saturation point, urate crystals may precipitate and deposit in joints, soft tissues, kidneys and other parts. When these needle‑like crystals suddenly trigger severe inflammation, causing redness, swelling, heat and pain in joints, it is an acute gout attack. Not all people with hyperuricemia will develop gout, but the higher and longer the blood uric acid level lasts, the greater the risk of gout attacks. Even if it does not develop into gout, long‑term high uric acid will still cause damage to kidneys and blood vessels.

 

Four Warning Signs Your Body Sends for High Uric Acid

If your blood uric acid level exceeds 420 μmol/L for a long time, your body may send out the following four warning signals:

Only elevated uric acid without other discomforts: This is asymptomatic hyperuricemia, the best intervention window. It is necessary to immediately start lifestyle intervention and regularly review uric acid and renal function.

Sudden severe pain and redness in big toe, ankle or knee: This is a typical acute gout attack. Seek medical attention immediately, do not take medicine without authorization. Avoid hot compress and massage, properly elevate the affected limb and apply ice compress to relieve symptoms.

High uric acid accompanied by foamy urine, backache and fatigue: It may indicate kidney damage. Urate crystals may deposit in the kidneys to form stones or block renal tubules, causing gouty nephropathy. Seek medical evaluation in time for stones or renal function damage.

High uric acid combined with elevated blood pressure, blood sugar and blood lipids: It belongs to metabolic syndrome. These conditions interact to greatly increase the risk of cardiovascular and cerebrovascular diseases. It is necessary to comprehensively evaluate multiple metabolic indicators and carry out integrated management under the guidance of doctors.

Long‑term high uric acid will aggravate liver oxidative stress, damage liver and kidney cells, and form a vicious circle of metabolic disorders. This is where the natural herb Cistanche Tubulosa plays an important role in assisting uric acid regulation and organ protection.

 

Scientific Intervention for High Uric Acid: Four Core Steps

The Dietary Guidelines for Adults with Hyperuricemia and Gout (2024 Edition) issued by the National Health Commission provides clear guidance. The following four core steps should be followed:First, seek medical evaluation immediately. Do not rely on home remedies or self‑medication. Go to the rheumatology or endocrinology department of a regular hospital for professional assessment.Second, adjust diet following the principle of three restrictions and three encouragements. Restrict high‑purine foods, high‑fructose foods and all kinds of alcohol. Encourage adequate water intake (2000–3000 ml per day for people with normal renal function), adequate intake of milk and dairy products, and sufficient fresh vegetables and fruits.Third, exercise scientifically to avoid acute injuries. During remission or asymptomatic period, choose aerobic exercises such as brisk walking, swimming and cycling. Avoid intense anaerobic exercises. During acute attack, absolutely rest, elevate the affected limb and apply local ice compress.Fourth, maintain regular work and rest and manage weight. Obesity is an important risk factor for high uric acid. Weight loss should be gradual. Rapid weight loss may induce gout. Stay up late less, because long‑term staying up late and stress will disrupt endocrine and affect uric acid metabolism.

 

Cistanche Tubulosa: Natural Support for Lowering Uric Acid Levels

For people seeking natural and safe auxiliary conditioning methods, Cistanche Tubulosa extract from traditional Chinese medicine has been confirmed by modern research to have positive effects on assisting uric acid control and protecting liver and kidney functions. Cistanche is beneficial for lowering uric acid levels, and its core active ingredients acteoside and echinacoside play a key role.

Studies have shown that acteoside and echinacoside in Cistanche can increase the activity of SOD, the core antioxidant enzyme in the body, inhibit apoptosis and necrosis of liver and kidney cells, reduce the levels of liver and kidney injury markers, repair damaged liver and kidney tissues, and regulate metabolic balance. They exert protective effects on liver and kidney injuries caused by various factors including chemical toxins, inflammation and overwork, and the efficacy is positively correlated with the dosage. At the same time, these active ingredients can inhibit the activity of xanthine oxidase, reduce uric acid production, promote uric acid excretion by regulating renal transporters, and help maintain normal blood uric acid levels.

For people with long‑term high uric acid, Cistanche Tubulosa extract can not only assist in lowering uric acid levels, but also reduce the oxidative stress and inflammatory damage caused by high uric acid to liver and kidneys, forming a dual protection of uric acid control and organ maintenance.
