This must be done preventatively, however, not to provide immediate relief. Use to boost your immunity - but do NOT use if you suffer from MS, AIDS, tuberculosis, lupus, rheumatoid arthritis or any other autoimmune disease. Echinacea should never be taken for more than 8 weeks at a time, I generally recommend 2 weeks on, one week of during use. Topically, Lavendar is most beneficial for it's antiseptic, antibacterial and would healing properties. But I can't emphasize enough the relaxation benefits of using Lavendar as aromatherapy as well.
Chamomile is another anti-stress, calming herb.
Very useful for combating insomnia, as well as in the treatment of coughs and colds, fever, sore throat, and tendency toward infection. Topically, chamomile also reduces the 'stress' of skin inflammations as well. Lemon Balm is especially effective in treating stomach upset and promoting relaxation. Used primarily to ease muscular tension and the pain of rheumatism. Nature's best remedy for coughs and colds, it also combats appetite loss, bronchitis, and indigestion.
