Hi doctor,

My brain is getting exhausted after reading books or journals or watching movies or TV continuously for a few hours. My mental exhaustion threshold is 80 to 85 % less than that of a normal person. It lasts for two to five days or more depending on the intensity. During that time my mind is not allowing me to go through the same activity and reacts very slowly. I am unable to concentrate, and many times I am involuntarily closing my eyes, that is, going to sleep. I have mental and muscular fatigue even for a small study or work. Due to this, I am sad and depressed. Hence, I stopped studying and felt better. My remote memory is also less. I am unable to recollect 10 % of what I read before five days. Please help me to fix my memory and early mental exhaustion. There is no history of a headache, insomnia, loss of appetite, or weight loss. My sexual desires are fluctuating. I was operated on for bilateral cataracts at the age of 18 years. I was under the tablet Venlafaxine 150 mg, for two years. I had done the sleep study, MRI brain, thyroid, CBC, 2D echo, treadmill, etc., which were normal. Since many medicines are available in homeopathy, help me to choose the right one as I need to prepare for the entrance exam, where I need to read for 15 hours a day.



Welcome to

Keeping your symptoms in view, my suggestions are as follows:

  1. The mind is related to our lifestyle and thinking. Try to relax and give yourself some time in between the things to avoid brain exhaustion. Try to make a timeline to reduce your stress and not to add.
  2. You can start taking Gelsemium 200, four drops in half a cup of water, and Kali phos 30X (Kali phosphorica) four tablets, thrice daily for a month. These are homeopathic medicines and are completely safe. Consult your specialist doctor, discuss with him or her, and start taking the medicines with their consent.
  3. You need to do some physical activity like brisk walking for 15 to 20 minutes, five times a week.
  4. You can also get a hemogram, TSH (thyroid-stimulating hormone), LFT (Liver function test) and RFT (Renal function test) done.

Thank you doctor,

I have to take Gelsemium 200 for how many days and how many times a day? I read online and felt that it will be a good medicine for me. It is mentioned that the patient would have insomnia, but I sleep well at night-time.



Welcome back to

Gelsemium 200, four drops thrice daily. It is a constitutional medicine and is used in various conditions.
