The immune system is an organism’s defence system against foreign substances and germs. It thereby fulfils an important task, as the constant interaction between the body and its surroundings mean that there are many bacteria, viruses, fungi, and parasites which must be repelled. Traditional medicinal plants like the ones found in our herbal liquids support the body’s natural defences and strengthen the immune system. Herbs with antibacterial properties also help to keep out invaders like bacteria and parasites. These herbs include bay laurel, horseradish root, thyme, oak bark, and teasel. Soothing herbs like marsh-mallow, sage, and fennel support natural respiratory function and help to prevent developing irritations.
