Is Eating Ginger at Night as Toxic as Arsenic? The Truth Behind the Claim

Ginger is a familiar spice in Vietnamese cuisine, but a common belief about when to eat it might not be entirely accurate.

 

 

For centuries, ginger has been highly valued for its health benefits. Even Hua Tuo, a famous Chinese physician, considered ginger a key to longevity. He once wrote: “Eating three slices of ginger in the morning is as beneficial as drinking ginseng soup.”

Vietnamese folklore also carries a saying: “Eating ginger in the morning is better than drinking ginseng tea, but eating it at night is as toxic as arsenic.” But is this really true?

What Do Experts Say?

Dr. Huỳnh Tấn Vũ from the University Medical Center of Ho Chi Minh City states that there is no scientific evidence in modern medicine supporting the claim that eating ginger at night is toxic. This idea has been passed down orally, but it lacks medical validation.

However, while eating ginger correctly can be beneficial, consuming it improperly may cause harm.

The reasoning behind eating ginger in the morning is that at this time, the stomach has more digestive energy. A small amount of ginger can stimulate digestion, boost circulation, and enhance metabolism.

On the other hand, eating too much ginger at night can lead to restlessness and internal heat, making it harder to sleep.

Dr. Vũ clarifies that the statement "eating ginger at night is as toxic as arsenic" is not entirely accurate, as traditional medicine still prescribes ginger in some nighttime remedies.

The Benefits of Ginger

Ginger is known for its warming properties, which can help with various ailments:

• Stomach pain due to cold digestion: Roast a ginger root and consume it.
• Severe abdominal pain spreading to the back or ribs: Boil 8g of ginger, 12g of mugwort, 12g of cinnamon, and 15ml of vinegar.
• Diarrhea or dysentery: Crush 8g of ginger and consume it with warm rice porridge (dosage: 4-12g).

Ginger is especially beneficial for postpartum women experiencing cold sensitivity, poor circulation, bloating, and heavy limbs.

It also has other medicinal uses:

✔ Promotes sweating and detoxification
✔ Warms the digestive system and reduces nausea
✔ Soothes the lungs and relieves coughs
✔ Helps detoxify the body

Additionally, ginger is effective for joint pain relief, particularly in winter. Consuming 5-10g of fresh ginger daily can significantly improve arthritis symptoms. Ginger-infused alcohol can also be used for external massage to increase blood circulation and reduce joint pain—but it should be used cautiously to avoid overuse.

Caution When Using Ginger

While ginger is widely beneficial, it can raise blood pressure, so individuals with hypertension should use it with caution. Overconsumption can also cause internal heat and discomfort.

Dr. Vũ advises that when using ginger as medicine, it’s best to consult a healthcare professional to ensure the correct dosage and avoid self-medicating, even with herbal remedies.
