Home treatments to care for your skin, herbs have been used for centuries as beauty aids and aids to general skin health and can still be useful natural alternatives to the ready-made things you find in the shops, that are full of synthetic chemicals. For instance, you can make up a chamomile wash, by pouring boiling water on a chamomile tea bag - cover and cool and use this to bathe irritated skin - it is usually best if you make a new infusion each time you need this - this can be helpful for acne rosacea where you need to treat the skin with care and where other cleansers may aggravate.
Similarly a few chamomile flowers in the bath can be soothing - or a strong infusion made up beforehand and added to your bath may even help with the itching of eczema! As an added bonus, this is also very calming if you have had a busy or fretful day. Do be a bit careful with chamomile, however, although it is a very safe herb, like everything a few people are sensitive to plants from the daisy family (Asteracea) so stop using if it cause you any irritation.
Psoriasis, eczema and other itchy skin conditions can also be soothed by putting a smallish amount (perhaps a couple of tablespoonfuls) of rolled oats tied up into the foot of an old (but clean!!) pair of tights, which is either put under the running tap as you fill your bath, or swished around in the water. It will release a milky liquid, which is surprisingly good for the skin (if you can use organic oats, as these will be free of any residual chemicals). Some of our grandmothers and great grandmothers and any amount of great great grandmothers, will have used this on a daily basis to keep their complexions sweet, rather than assaulting their skins with harsh soaps that can leave residues and alter the delicate balance of the skin surface, which can lead to problems.
