Clotting problems: Water dock might make blood clot faster than normal.
Kidney disease: The oxalate crystals in water dock might form kidney stones. If you have a history of kidney stones or other kidney problems, it's best to avoid using water dock. It could make your condition worse.
The appropriate dose of water dock depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for water dock. Keep in mind that natural products are not always necessarily safe and dosages can be important.
