1. Clove - Clove has the power to kill nasty germs and fungus. A study in the Annals of Microbiology concludes clove essential oil has anticariogenic activity against a large number of oral pathogens. Clove neutralizes harmful Staphylococcus bacteria (“staph” infections) as well as E. coli (the same bacteria responsible for food poisoning), as well as Candida albicans. The main natural chemical in clove, eugenol, has been shown to have anti-inflammatory activities stronger than over-the-counter NSAIDs.
2. Lemon - Lemon contains broad-spectrum antiviral activity. That means it protects you against several different kinds of viruses, such as those that cause colds and the flu. Lemon also greatly assists the body’s detoxification processes. An active ingredient in lemon, linalool, has antibacterial properties, especially against a nasty bug called “acinetobacter,” which can cause serious infections and antibiotic resistance.
3. Cinnamon - Cinnamon boosts your respiratory system and protects you against unfriendly bacteria in your body. A compound in cinnamon called “cinnamic aldehyde” is the active ingredient that kills several harmful types of fungi, including Aspergillus niger, aka “black mold.” And in studies using cell lines, cinnamon has been shown to suppress the growth of tumors.
4. Eucalyptus - Eucalyptus has been used for centuries to help people breathe easier. A particular species of it, eucalyptus globulus, has been shown in research studies to help inhibit several types of bacteria that can make you very sick, such as H. influenzae and S. pneumoniae.
5. Rosemary - Rosemary improves your immune system as it reduces muscle pain and the inflammation response. It also breaks up mucus throughout the body. Laboratory studies reveal the antioxidants in rosemary neutralize free radical damage.
