Bruises develop when the tissues under the skin get damaged and blood collects in that area. Although it is normal to develop bruises when you have been hit or knocked down by a hard object, some people tend to develop bruises easily. This is due to deficiency of nutrients and anemia. Supplements containing vitamin C, bioflavonoids, vitamin B complex and iron are especially useful for people who tend to bruise easily. You can take a multivitamin and mineral supplement to help with bruising. Detoxifying supplements like algae supplements, antioxidant supplements like acai berry supplements can also help reduce bruising. Some herbal supplements widely used for bruising are arnica, calendula and comfrey. Arnica can be applied topically on the bruised area. It is available in the form of pastes, ointments, tinctures. It helps reduce inflammation and promotes wound healing. Calendula is available in the form of ointments, washes and tinctures. It can be applied over the bruise to promote healing. It has potent antioxidant effects and also enhances blood flow to the wounded area, thereby reducing bruising. Comfrey is useful to treat the inflammation and promoting cell regeneration, thereby helping the bruise to heal properly. This is applied in the form of ointment over the affected area and can restore natural color to the skin much faster than normal healing time.
