Poison Ivy/Oak/Sumac
Published in Charles Theisler, Adjuvant Medical Care, 2023
Poison ivy, oak, and sumac are common poisonous plants on the North American continent. When these plants are touched, they deposit an oily sap called urushiol onto the skin. The sap is noted for its ability to create a localized type of allergic contact dermatitis with an uncomfortable, red, itchy, blistery rash. Poison ivy, oak, and sumac rashes are not contagious and cannot spread from one person to another even if there are open sores, because blister fluid does not contain urushiol. Only if another person touches the urushiol that is still on the affected person or his or her clothing can the rash be acquired.

Aloe vera, tulsi, neem, turmeric, and mint are examples of commonly used medicinal plants for home remedies in many regions of the country. Besides having medicinal properties, herbs are also used in pest control, natural dye, food, tea, perfume, and so on.

In another study, 35 indigenous medicinal plants were identified in Urmia, Iran that were effective against infectious diseases of urinary, reproductive, digestive, respiratory tracts and the skin. Those plant species belonged to 17 plant families and the Lamiaceae had the highest frequency of plants for the treatment of infectious diseases. Althaea hirsuta, Mentha longifolia were some examples of plant species that had been used against pulmonary infections. Alhagi camelorum and Glycyrrhiza glabra were commonly used against intestinal infections while Dipsacus laciniatus and Equisetum arvense were used against urinary tract infections. Lamium album was employed as a remedy for both urinary tract infections and vaginitis. Some examples of plants that have been used against skin infections included Sanguisorba minor, Verbascum agrimonifolium and Ixiolirion tataricum. Plant leaves were the most widely used part in preparation of herbal remedies and most of the medicinal herbs were prescribed in the boiled forms (Bahmani et al. 2015).

Principally, traditional Chinese medicinal plants are considered to have stronger medicinal values compared with common fruits or vegetables. In this respect, along with ginseng and ginger as the most common plants, other kinds of these medicinal plants such as astragalus and kudzu (Pueraria lobata) are also investigated. Yang et al. (2023) reported turmeric-derived exosomes loaded with astragalus components (Astragaloside IV and Calycosin) in order to enhance their oral absorption and synergistic tumor suppressive effect. Further, Wu et al. (2022) also demonstrated the potential impacts of kudzu-derived PELNs in regulating pro-inflammatory responses via miRNAs delivery to immune cells. Other examples of PELNs as new drug delivery systems for specific targets are shown in Table 10.

As can be appreciated, it is necessary to seek alternative treatments for peptic ulcers. Medicinal plants are one of the principal sources of new compounds with therapeutic activity (Torres-Rodríguez et al. 2016). Heliotropium indicum L. (Boraginaceae) is a traditional medicinal plant that contains tannins, saponins, steroids, oils, and glycosides, and has been employed to clean and heal wounds, alleviate fever, relieve eye infections, and treat menstrual problems, nervous disorders, kidney disease, and ulcers (Adelaja et al. 2008; Nethaji et al. 2013). Since the key compounds responsible for the gastroprotection activity of the plant have not yet been identified, the aim of the current contribution was to isolate, through a bioassay-guided study, at least one such compound, evaluate it with ethanol-induced gastric lesions in mice, and explore the possible participation of prostaglandins, NO, and sulfhydryl groups in its mechanism of action.

Aromatherapy is a complementary treatment that uses aromatic essential oils extracted from plants, and is recognized to promote relaxation and relieve anxiety.5 The essential oils used in aromatherapy are absorbed through the skin following topical application or sensed by the olfactory system following direct inhalation or slow diffusion (such as when applied to clothing or jewelry). Olfactory stimulation is a simple and effective treatment for certain physiological problems, such as anxiety, pain, and poor sleep quality.6–8 Aromatherapy uses extracts from a variety of plants, such as lavender and chamomile. These interventions consist of different doses of essences (volatile oils) that are administered by inhalational, oral, or topical methods. Aromatherapy is simple, easy to apply, and requires minimal training of practitioners.
