The Issues of Allergies
Several medicinal herbs belong to botanical families that, unfortunately, can cause allergies in some people. The Asteraceae/Compositae family contains many medicinal plants — and a few common allergens. If you're allergic to ragweed, marigolds, or daisies, avoid these herbs:
Arnica (Arnica montana)
Artichoke (Cynara cardunculus, C. scolymus)
Butterbur (Petasites hybridus)
Calendula (Calendula officinalis)
Chamomile (Matricaria recutita)
Dandelion (Taraxucum officinale)
Echinacea (Echinacea purpurea)
Eclipta (Eclipta alba, E. prostrata)
Feverfew (Tanacetum parthenium)
Milk thistle (Silybum marianum)
Yarrow (Achillea millefolium)
Salicylic acid is part of a group of chemicals called salicylates, which occur naturally in many plants and are also produced synthetically for use in a variety of consumer products.
Salicylates are everywhere. They can be found in many skin care products, including acne treatments, perfumes, and sunscreens, as well as aspirin, antidiarrheal medications, toothpastes, and OTC sports creams. They're also in a variety of foods, including berries, red wine, and pine nuts. To someone with sensitivity, even a tiny dose can cause a serious reaction.
Many people are sensitive to salicylates, and so should avoid them in all their incarnations. Skip salicylates if you're taking prescription blood thinners or diabetes medications. Herbs with salicylates include:
Cayenne (Capsicum annuum, C. frutescens)
Cinnamon (Cinnamomum verum, C. aromaticum)
Clove (Syzygium aromaticum)
Fenugreek (Trigonella foenum-graecum)
Ginger (Zingiber officinale)
Grape (Vitis vinifera)
Grapefruit (Citrus paradisi)
Licorice (Glycyrrhiza glabra)
Peppermint (Mentha x piperita)
Sage (Salvia officinalis, S. lavandulaefolia)
Turmeric (Curcuma longa)
Willow (Salix alba)
