Dear @Gourav_Rana,
As mentioned in other threads, there is no conclusive medical or scientific evidence that shows Ayurvedic medicine works any better than placebo in trials (and in some cases they can be dangerous to liver health) Alternative medicines and "cures" for Hepatitis B - #4 by ThomasTu. There is no law guaranteeing what is included in these medicines, so you are never sure you are getting what is labelled on the bottle (even if you trust the person who is selling it, there is no guarantee from anyone along the whole supply chain).
Even things that are safe for many people can affect you in unknown ways. As mentioned in other threads, something as innocuous as a grapefruit can cause severe cross-reactions with many drugs. It is best to talk to your doctor about this.
It is unlikely that Vemlidy will cause your fibroscan to permanently be elevated. Indeed, trials show antiviral treatments will reverse liver damage in the long term (as it allows the liver to heal itself by preventing additional damage).
Thomas
