Like Sugarmag, I've found Arsenicum to be fantastic for DD1, if she gets a bug. IMO it's amazing, I've never seen anything work so quickly or effectively.
I do think that Arsenicum (as with most homeopathy) is effective only with specific types of people though, unlike Arnica.
It did nothing for a friends son.
At home, I keep Arsenicum, Arnica (pills and cream), Belladonna, Gelsemium, and some 'New Era' mixes. Some other creams, Calendula, Hypercal and my Helios birth kit (Aconite, Arnica, Bellis Per, Calendula, Carbo Veg, Caulophyllum, Chamomilla, Cimicifuga, Gelsemium, Hypericum, Ipecachuana, Kali Carb, Kali Phos, Phytolacca, Pulsatilla, Secale, Sepia, Staphisagria) comes in handy occasionally, though they are all @ 200c.
I use Aromatherapy daily, I have a friend who's an Aromatherapist and she makes up some fantastic creams! I do Reiki.
Echinecea and Rescue Remedy are often in use!
Thanks for the Mimulus tip, Beccalanismum! My DD1 tends towards anxiety, I might give this a go
