“…Decoctions from the rhizomes of P. aquilinum are drunk as a herbal health tea, and the rhizomes of W. unigemmata are used to cure skin diseases. Leaf juices are used as a tea or bath for curing infertility in women, for abdominal pain, constipation and sore throats (Nwosu, 2002). A paste of leaves and rhizomes mixed with lukewarm milk for 30 d is used as an effective tonic.…”

Abstract:The aim of this review was to explore the pharmacological activity of early tracheophytes (pteridophytes) as an alternative medicine for treating human ailments. As the first vascular plants, pteridophytes (aka, ferns and fern allies) are an ancient lineage, and human beings have been exploring and using taxa from this lineage for over 2000 years because of their beneficial properties. We have documented the medicinal uses of pteridophytes belonging to thirty different families. The lycophyte Selaginella sp. was shown in earlier studies to have multiple pharmacological activity, such as antioxidant, anti-inflammatory, anti-cancer, antidiabetic, antiviral, antimicrobial, and anti-Alzheimer properties. Among all the pteridophytes examined, taxa from the Pteridaceae, Polypodiaceae, and Adiantaceae exhibited significant medicinal activity. Based on our review, many pteridophytes have properties that could be used in alternative medicine for treatment of various human illnesses. Biotechnological tools can be used to preserve and even improve their bioactive molecules for the preparation of medicines against illness. Even though several studies have reported medicinal uses of ferns, the possible bioactive compounds of several pteridophytes have not been identified. Furthermore, their optimal dosage level and treatment strategies still need to be determined. Finally, the future direction of pteridophyte research is discussed.

“…Sonst ist die Verwendung von Pteridophyten als Lebensmittel auf unserem Kontinent in Vergessenheit geraten - mit der kleinen Ausnahme, dass die Rhizome des Engelsüss ( Polypodium vulgare L.) mit ihrem an Lakritze erinnernden Geschmack als bescheidene Schleckerei gekaut werden können. In Ostasien gelten die Bischofsstäbe der Adlerfarne und von verwandten Arten als Delikatesse und werden ähnlich wie Spargel zubereitet [10], ebenso in Nigeria [11] und im Kongo [12]. Indigene Völker in den südwestlichen USA sammeln die Rhizome der Adlerfarne als Stärkespeicher, ähnlich wie bei uns die Kartoffeln [13].…”

In dieser Arbeit wird die ethnomedizinische und ethnobotanische Bedeutung von Gefässkryptogamen, d.h. Farne, Bärlappe, Moosfarne, Schachtelhalme, Brachsenkräuter und Urfarne, in verschiedenen Kulturen beschrieben. Die gegenüber Samenpflanzen artenarme Gruppe spielt weltweit als Nährpflanzen für Menschen eine kleine Rolle, doch sind die Gefässkryptogamen als Heilpflanzen recht bedeutungsvoll. Durch ihren lange Zeit unverstandenen Fortpflanzungsmechanismus ohne Blüten, Samen und Früchte wurde den Farnen und ihren Verwandten in früheren Zeiten eine gewisse Magie zugeschrieben. Diese Zauberhaftigkeit verschwand in Europa mit dem Fortschreiten der Naturwissenschaften seit der Aufklärung; in anderen Regionen der Welt konnte sie im Bewusstsein der Menschen bis heute bewahrt werden.

“…The plant has also been reported to increase the size of the male reproductive organ through mechanisms yet unknown (Kantemir, Akder & Tulunay 1976); however, this action may be suggestive of an oestrogenic or androgenic effect. The young coiled fronds of the plant are used in different parts of Nigeria as an antihelminthic, and infusion of the leaves is additionally used as an aphrodisiac (Nwosu 2002). The plant has also been reported to have potent antioxidant and cytotoxic activities (Sekendar Ali et al 2012), insecticidal activity (Shukla & Tiwari 2011) Based on its reported use in postpartum haemorrhage and uterine stimulation, this study sets out to verify this use and examines some parameters on possible mechanisms of activity.…”

Background: The plant Dryopteris filix-mas has been used traditionally for its uterine-stimulant effects.Aim: The current study is therefore aimed at investigating and determining the effect of the leaves of D. filix-mas on uterine contractility in vitro.Setting: Fresh leaves of D. filix-mas were collected from a river bank in the south-western part of Nigeria.Methods: The leaves of D. filix-mas were cleaned, dried and extracted in methanol. The extract (0.07 µg/mL–21.0 µg/mL) was tested on the isolated mouse uteri in order to determine activity on spontaneous-induced uterine contractions. Subsequently the extract (0.005 mg/mL and 0.05 mg/mL) was tested on oxytocin-induced contraction (0.00017 ng/mL–4.98 ng/mL) in calcium-containing media, submaximal oxytocin-induced contraction (0.116 ng/mL) in calcium-free media and in the presence of high KCl-induced uterine contractions (80 mM). The extract was also subjected to mass spectrometric determination of secondary metabolites.Results: The plant extract inhibited spontaneous-induced contractions with IC50 amplitude = 658.41 ng/mL ± 0.11 ng/mL and IC50 frequency = 175.32 ng/mL ± 0.53 ng/mL. The plant extract inhibited oxytocin-induced and high KCl-induced uterine contractions (p < 0.01 at 0.5 mg/mL). The plant extract had no effect on oxytocin-induced contractions under calcium-free conditions. Secondary metabolites belonging to classes of fatty acids, alkaloids, saponin glycosides, amino acids, limonoids, terpenes and porphyrins were identified.Conclusion: The current study reports an inhibitory effect of the plant on uterine contractility in this study, suggesting possible application as a tocolytic or as a contraceptive, as most contraceptive plants have shown uterine-relaxing effect.
