Introduction
Under normal circumstances, the property of luffa (sponge gourd) is typically cool in nature. Luffa is not recommended for individuals with spleen and stomach deficiency-cold or those prone to diarrhea, as excessive consumption may exacerbate gastrointestinal discomfort. Spoiled or rotten luffa should never be eaten to avoid food poisoning caused by microbial contamination. When cooking luffa, ensure it is thoroughly cooked, as undercooked luffa not only has an unpleasant texture but may also irritate the gastrointestinal tract.

Generally speaking, luffa is typically considered to have a cooling property. The detailed explanation is as follows:

In traditional Chinese medicine, luffa is described as having a cool nature and a sweet taste, acting on the lung, liver, and stomach meridians. Due to its cooling properties, luffa can clear internal heat, cool the blood, detoxify, and relieve constipation, making it suitable for individuals experiencing excessive internal heat or constipation. Additionally, it helps promote blood circulation and alleviate conditions such as irregular menstruation and insufficient lactation in women. From a nutritional perspective, luffa is rich in vitamin C, B vitamins, dietary fiber, and minerals such as potassium and magnesium. Vitamin C helps boost immunity, while dietary fiber promotes intestinal motility, both contributing to overall health benefits. Moreover, luffa contains polysaccharides and flavonoids, which provide antioxidant and anti-inflammatory effects.

As luffa has a cooling nature, it is not recommended for individuals with spleen and stomach cold deficiency or those prone to diarrhea to consume in large amounts, as it may worsen gastrointestinal discomfort. Spoiled or rotten luffa should never be consumed to avoid microbial contamination leading to food poisoning. When cooking luffa, ensure it is thoroughly cooked, as undercooked luffa not only has an unpleasant taste but may also irritate the gastrointestinal tract. Individuals allergic to luffa should avoid consuming it to prevent allergic reactions.
