I've been drinking similar tea blends to these pictured for years to help with skin problems, to naturally whiten my teeth (yes!) and help me with better sleep. Be sure to consult with your GP first before adding any of these teas to your diet as they are not suitable for some. Especially pregnant women.
Gotu Kola (Centella Asiatica) has been known as a healing herb for thousands of years. It can heal wounds, improve mental function and fight insomnia. Gotu Kola has also been known to fight symptoms of inflammatory and rheumatoid diseases.
In terms of healing skin Gotu Kola can: Increase the strength of the dermis, prevent skin from tightening too much while a wounds heals (this tightening of the skin can cause scarring), enhance the production of things like mucin in the body which helps the production of connective tissue.
Calendula has natural astringent and antibiotic properties which make this flower a great skin healer. The anti-inflammatory properties can help with acne and other issues. Calendula can also be used as a mouthwash to help heal gingivitis and other gum/dental problems! I like to mix Calendula with Gotu Kola and Licorice Root tea for an all over healing blend. Although don't drink Calendula if you are pregnant as it can stimulate menstruation!
For whiter teeth, Licorice Root Tea is your best friend. I find that the raw, chopped root form is strongest as a whitening agent. Consumption of Licorice Root Tea should be limited to two cups per day, as overuse can lead to some scary health problems! Do not drink Licorice root tea if you are pregnant.
Aside from whitening teeth and acting as a painkiller, Licorice Root Tea can help with coughs, bronchial disorders and help maintain body weight. It can also help treat low blood pressure and fight the plaque forming in blood vessels that may lead to heart disease.
For better sleep, try a mix of Chamomile and Passionflower. Passionflower can be used to help sleep disorders or for a more restful sleeep. It boosts production of the brain chemical GABA, lowering anxious brain activity and helping us ease into sleep more. It also aids in gastrointestinal disorders. Chamomile soothes the nervous system to promote healthy sleep. Both these plants also promote healing of wounds and good skin health, drink 1-2 cups before bed to relax, and wake up feeling refreshed.
You can also try a mix of passionflower, lavender and damiana for better sleep, damiana tastes like cordial and can be served iced in summer!
I typically buy my herbs in loose leaf form, mix them up together and store the mixtures in jars.
