Complementary and alternative medicine therapies, such as acupuncture, biofeedback, chiropractic manipulation, dietary supplements, herbal therapy, and homeopathic preparations, are used by individuals with allergic rhinitis.29,30 Use of bromelain, gingko, ginseng, licorice, quercetin, and Urtica dioica has been reported, but large-scale studies documenting efficacy are lacking.31,32 Caregivers should inquire routinely about patients use of alternative therapies and counsel patients about the lack of validated data to support such practices.12... 

Allergenic plants causing skin eruption by contact include poison ivy (Rhus radicans L.), poison oak (Rhus toxicodendron L.), poison sumac (Rhus vernix L.), and stinging nettle (Urtica dioica L.). In the United States, poison ivy and poison oak cause nearly 2 million cases of skin poisoning and skin irritation annually, for a loss of 333,000 working days. In addition, these weeds cause 3.7 million days of restricted activity among those people who are susceptible to the toxins (1).

Lectins The mannose-specific plant lectins from Galanthus, Hippeastrum, Narcissus, Epipactis helleborine, and Listera ovata, and the V-acctylglucosaminc-spccilic lectin from Urtica dioica would primarily be targeted at the virus-cell fusion process. 

A number of mannose-specific agglutinines (lectins) from Galanthus nivalis, Hippeastrum hybrid, Narcissus pseudonarcissus, Listera ovata, Cymbidium hybrid, Epipactis helleborine, and the N-acetylglucosamine-specific lectin from Urtica dioica have been found to inhibit HIV-1 and HIV-2 infection at similar concentrations as dextran sulfate (IC50 0.2 to 0.6 fig/ml), or even lower (IC50 0.04 to 0.08 pg/ml. Akin to sulfated polysaccharides, the plant lectins also exhibit activity against various enveloped viruses other than HIV, i.e., HSV-1, HSV-2, CMV, RSV, and influenza virus. Plant lectins would primarily interfere with the virus-cell fusion process. Their precise mode of action remains to be resolved.

Chlorogenic acid is one of the active components in a herb Urtica dioica L. (Urticaceae) and has been utilized for the treatment of rheumatoid arthritis. Chlorogenic acid from the plant demonstrates moderate inhibitions against the 5-LOX pathway with IC50 = 83 pM and COX pathway with IC50 = 38 pM [163]. However, caffeic acid has been reported as a weak inhibitors against 5-LOX (IC50 = 200 pM) and showed no inhibition on COX pathway [164].
