To cleanse and protect the liver as well as for liver damage from the Candida toxin, aldehyde, the recommended dose of milk thistle is 420 mg/day containing at least 70-80% silymarin. Silymarin is a flvonoid that is extracted from the seeds of milk thistle and is the beneficial part of the herb.
The highest amount recommended is 560 mg/day for 16 days; after 16 days the dose can be reduced to 430 mg a day. This amount is recommended for intrahepatic cholestasis treatment, but the same amount could be taken if severe liver damage is suspected. The dose you decide to take should be spread out over approximately a 16 hour period.
At these doses, the herb will bind with as well as coat the liver cells, and the photochemical properties can heal any previous liver damage as well as protect the liver from future damage. The silymarin shields the liver from toxic substances. This flavonoid also encourages the liver to grow new cells. Milk thistle capsules can be taken throughout your treatment
As with all herbs, an allergic reaction to milk thistle is possible. In this case your body mistakes silymarin, the flavonoid contained within milk thistle, for a harmful toxin and raises histamine levels in an attempt to destroy it. An allergic reaction could possibly cause hives or persistent itching, and in more serious cases, swelling of the face, neck and throat; difficulty breathing and heart palpitations are rarer but still a possibility. For these reasons, you should start with the lowest dose possible and work up to the higher dose.
