15秒盐水法是什么？它对勃起有效吗？

📝 事实核查: This is a viral myth with no scientific basis. 🙅‍♂️ There is no credible evidence that consuming salt, either by drinking it or putting it under your tongue, can treat erectile dysfunction (ED), let alone in 15 seconds. In fact, medical advice is generally the opposite: high sodium intake is a risk factor for high blood pressure, which can damage blood vessels and worsen ED. The body's mechanisms for achieving an erection are complex and involve the nervous and vascular systems; a pinch of salt cannot instantly trigger this process.
