Phytodysfunction can lead to physical weakness. Phytodysfunction, also known as autonomic nerves, includes sympathetic and vagus nerves, which are two groups of nerves that mainly govern somatic and visceral activities. Phytodysfunction can lead to symptoms of multiple systems throughout the body, such as generalized weakness, insomnia, dreaminess, mental laxity, emotional indifference, memory loss, menstrual disorders, low libido, dizziness, headache, chest tightness, heartburn, abdominal pain, diarrhea, and loss of appetite. Among them, generalized weakness is one of the most common symptoms, and this disease is mostly seen in elderly or female patients around 50 years old. Currently, drugs regulating plant nerve function such as glutamate and B vitamins as well as anti-anxiety and depression drugs such as paroxetine and citalopram are commonly used clinically to treat generalized weakness symptoms caused by plant nerve dysfunction.
