Sugarcane Juice with Lemon Grass and Ginger: What Experts Say About Blood Circulation Claims

Dr. Le Thi Huyen, head of the nutrition department at 19-8 Hospital in Vietnam, has warned that claims circulating on social media about sugarcane juice infused with lemon grass and ginger improving blood circulation or treating cold hands and feet lack scientific basis, according to a report by VietnamNet.

What Do Experts Say About the Claims?

Dr. Huyen emphasized that phrases like “blood replenishment” or “blood revival” are not recognized medical terms. “There is no evidence that a single glass of sugarcane juice with lemon grass and ginger can stimulate red blood cell production or significantly increase hemoglobin levels,” she stated. The claim that the drink can “restore blood” is scientifically unfounded, as human blood production relies on specific nutrients like iron, vitamin B12, and folate, not sugar or herbal additives.

According to the U.S. National Institutes of Health (NIH), red blood cell formation requires iron, which is found in red meat, liver, and plant-based sources like lentils. Vitamin B12 and B9 (folate) are critical for DNA synthesis in blood cells, while protein supports hemoglobin structure. “Sugarcane juice provides carbohydrates, not these essential nutrients,” Dr. Huyen explained.

Why Do People Feel a Temporary Boost?

The perceived energy surge and warmth after drinking the beverage stem from its high sugar content and the thermogenic properties of ginger and lemon grass. A 250–300ml serving of sugarcane juice can contain 30–50 grams of sugar, far exceeding the World Health Organization (WHO)’s recommendation of 25 grams of free sugars per day for adults.

“The sugar spikes blood glucose, providing quick energy, while ginger and lemon grass dilate blood vessels, creating a warm sensation,” Dr. Huyen said. However, these effects are short-lived and unrelated to blood regeneration. “It’s a sensory illusion, not a medical solution,” she added.

What Are the Health Risks of Sugarcane Juice?

Excessive consumption of sugarcane juice poses significant health risks. The U.S. Centers for Disease Control and Prevention (CDC) warns that high sugar intake can lead to insulin resistance, type 2 diabetes, and fatty liver disease. A single serving of the drink can exceed daily sugar limits, increasing the risk of metabolic disorders.

“This isn’t just about blood circulation,” Dr. Huyen said. “Overconsumption can trigger pancreatic stress, weight gain, and long-term cardiovascular issues.” She advised moderation and cautioned against using the drink as a substitute for proven treatments for anemia or circulatory problems.

What Should People Focus on for Healthy Blood Circulation?

Experts recommend a balanced diet rich in iron, B vitamins, and protein to support blood health. Foods like spinach, fortified cereals, eggs, and lean meats are more effective than sugarcane juice. Regular exercise, hydration, and avoiding smoking also improve circulation, according to the American Heart Association (AHA).

“If you’re concerned about blood health, consult a healthcare provider rather than relying on social media trends,” Dr. Huyen urged. “Natural remedies can complement treatment, but they shouldn’t replace medical advice.”
