So the top 10 herbs that could help are:
Ashwagandha: an adaptogen & it's key ability is to soothe frayed nerves & reduce spasms & inflammation.
Chamomile: we all know what a soothing herb this can be & a mild sedative in it's own right, but it also has anti-spasmodic properties.
Devil's Claw: native to southern Africa...the roots are used in medicinal preparations. it's an anti-inflammatory & has been found useful in the treatment of arthritis, rheumatic-type pain, neck & back pain, osteoarthritis & also tendonitis.
Echinacea: boosts the immune system and helps to reduce inflammation.
Elderberry: a powerful diaphoretic which means it induces sweating, thereby reducing fevers. It's a potent immune-system booster & very beneficial during the flu season.
Eleuthero: formerly called Siberian ginseng, it is actually NOT in the Panax ginseng family. The root, stem & bark are used in herbal medicine. It is an adaptogen and helps to increase endurance & stamina while also strengthening the immune system. It also acts as a nervine to help treat insomnia and frequent nighttime wake-ups. Some herbalists may also recommend it for chronic fatigue, immune deficiency & adrenal fatigue.
Licorice Root: another adaptogen & it helps by reducing inflammation and relieving adrenal exhaustion, depression, lethargy & fatigue. It also reduces excessive immune-system response which can lead to inflammation. If you have HBP, kidney issues or take prescriptions, check with your doctor first.
Milky Oats: these are extracted from the immature seed of the common oat, which is the same as your basic oatmeal, which fills with white "milk" for one week out of the growing cycle. But they serve as an excellent tonic for the entire nervous system, helping to restore frayed nerves & provide a sense of calm & tranquility. It is especially helpful for those who suffer from chronic fatigue, panic disorders, depression & insomnia.
Valerian: this one is a very strong sedative with pain-relieving actions. It is very useful for those suffering from stress, insomnia, pain from muscle spasms, tension, headaches & other similar issues. If you feel greater agitation after taking it, then of course discontinue taking it.
Willow Bark: the bark of this tree contains salicin which is the pain-reliever pharmaceutical companies extract for their aspirin. But unlike theirs, this will not cause gastrointestinal issues.
As with any of these, check with your doctor first, if you are so inclined.
