Can ashgourd stimulate the sinus infection?

No, ash gourd does not stimulate sinus infection. Ash gourd juice simply works as a powerful detoxifier that acts like a magnet for the toxins in your body. The cough and cold that manifests as a symptom of sinus infections are a way for Mother Nature to eliminate the toxins accumulated inside the body.

Remember, cold and cough are both happy diseases. They are detox symptoms. They are good signs. If you have one of these, it is a sign that your praanshakti has started the cleansing process inside. 

In case your symptoms are aggravated during the fast, here are some easy things you can do to get rid of the cold/cough - 
- Please take proper rest and continue the fast. 
- If you have wet pack, apply it thrice a day.
- If you have an enema, take the enema twice a day - once in the morning & once in the evening. 
- Sunbathe for 30 minutes every day (only in the light morning/evening sun)
- Do not consume any food or medicines.

To understand all of these steps in detail, please watch this video - https://www.youtube.com/watch?v=CZDgxv1plfw

You will see that the problem will automatically go within 2-4 days, once the body has been detoxified.
