How does one use a remedy? Drink it? Sniff it? Apply it to the skin?
The remedies come as a liquid, preserved in brandy. To take them, you dilute two drops of each remedy that you need into a 30ml dropper bottle, top up with mineral water, and take four drops four times a day. Alternatively, you can put the two drops into a glass of water, and sip from that at intervals.

How are they made?
Two methods are used to make the Bach Flower Remedies. Most of the more delicate flowers are prepared using the sun method, which involves floating the blooms in pure water for a number of hours. More woody plants, or flowers which bloom when the sun is weak, are prepared by boiling for half an hour. In both cases full-strength 40% brandy is used as a preservative, mixed 50/50 with the prepared tincture. Drops from the preserved mother tincture are further diluted in brandy to make the stock bottles that can be bought in the shops.
