Argyreia nervosa

(Redirected from Elephant creeper)

Argyreia nervosa is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic and medicinal value.[3] Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences.[4][5] The two botanical varieties are Argyreia nervosa var. nervosa described here, and Argyreia nervosa var. speciosa, the roots of which are used in Ayurvedic medicine.[3][6]

Argyreia nervosa contains various ergoline alkaloids such as ergine.[7] A study reported stereoisomers of ergine to be found in the seeds at a concentration of 0.325% of dry weight.[8] Two modern studies from a team of researchers also revealed lysergic acid,[9] methylergometrine (syn. lysergic acid butanolamide), methysergide, lysergylalanine, and suspected, unidentifed ergopeptines.[10] A study of the related Ipomoea tricolor showed that ergoline concentrations in the leaves are 12-fold lower than that of the seeds.[11]

History

edit

While seeds of other Convolvulaceae, specifically Ipomoea corymbosa (ololiuhqui) and Ipomoea tricolor (tlitliltzin), were used in shamanic rituals of Latin America for centuries, A. nervosa was not traditionally used for this purpose. Its properties were first brought to attention in the 1960s.[citation needed]

Cultivation

edit

Where temperatures fall below 13 °C (55 °F), Argyreia nervosa is grown in a warm greenhouse. Elsewhere, it is grown on arbours, pergolas, walls, or trees. It is often grown professionally under glass in a loam-based potting compost (John Innes No. 3) in full light, and watered freely from spring to autumn, with a balanced liquid fertilizer applied monthly and reduced water in winter. It is grown outdoors in moderately fertile, moist but well-drained soil in full sun. Pruning is done in late winter.[12]

Entheogen

edit
 
Hawaiian baby woodrose seeds

Certain New Age sources claim that, according to 'various oral histories' Huna shamans used the powdered seeds to prepare an entheogenic drink.[14] This is unlikely to reflect an authentic practice having once formed a part of traditional Hawaiian Religion,[15] given that Huna has been widely discredited as a culturally appropriative New Age religion invented by Max Freedom Long.[16] The seeds of Argyreia nervosa can produce psychoactive effects, but it has not yet been demonstrated satisfactorily that their use as an entheogen predates the various countercultural movements of the 1960s.[15] Given that A. nervosa is not native to Hawaii, having been introduced there from India, any Hawaiian practices involving it are unlikely to be of any antiquity. It cannot, however, be ruled out that the plant may have been utilised as an intoxicant in its native India at some time in the past, although evidence for this (if present) has not yet come to light.[15] The seeds of A. nervosa contain ergot alkaloids varying considerably in concentration with LSA weight ranging between exactly similar looking seeds from 3 μg to 34 μg (avg 17 μg).[17] However, in its effects, LSA is about one tenth as potent as its cousin LSD, making a threshold dose level for LSA (D-Lysergic Acid Amide) about 500 μg.[18] The psychoactive effects of the seeds may therefore be due to other alkaloids present in them and the safe and effective dose may be difficult to predict.

Uses in the traditional medicine of India

edit

While he does not claim there to be any evidence for the use of the seeds of A. nervosa as a traditional entheogen in its native India, Christian Rätsch does describe some interesting traditional uses of the root of the plant in Ayurveda somewhat suggestive of effects upon the CNS:[15]

The root is regarded as a tonic for the nerves and brain and is ingested as a rejuvenation tonic and aphrodisiac to increase intelligence.[15]

Other traditional uses are in the treatment of gonorrhea, strangury, chronic ulcers, diabetes, anemia, and cerebral disorders. The plant is also used as appetizer, brain tonic, cardiotonic, and aphrodisiac. It possesses anti-inflammatory, immunomodulatory, antibacterial, antiviral, and antifungal activities [19]

    “Additionally the presence of the ergot alkaloid diastereomers chanoclavine I and II was assumed in DF (cf. Fig. 6) together with traces of lysergic acid and the isobars lysergol, isolysergol, elymoclavine, molliclavine, setoclavine, or isosetoclavine.” (3.1. Mass spectrometry data, p. 65)
    “Indications of traces of [M+H]+ = 255.15 0.01 corresponding to lysergol/isolysergol, elymoclavine, setoclavine/isosetoclavine or molliclavine as well as [M+H]+ = 269.13 0.01 corresponding to lysergic acid were only obtained in the DF extracts and the resolution and the quality of the EICs and product spectra was poor. Therefore, the presence of lysergol/isolysergol, elymoclavine, setoclavine/isosetoclavine, molliclavine or lysergic acid cannot be excluded, but proof cannot be provided and additional research will be necessary.” (3.1.

    “On the other hand, methylergometrine, methysergide, and lysergylalanine were detected, which have not yet been reported as compounds of Argyreia nervosa seeds. Furthermore, some high molecular weight ergot alkaloid derivatives and hydroxyalanine derived ergopeptide fragments could be observed at various retention times (c.f. chapter 3.1). Altogether, lysergylalanine, the high molecular weight ergot alkaloids and the hydroxyalanine derived ergopeptide fragments strongly suggest the presence of ergopeptides in Argyreia nervosa. However, due to the disadvantage of the applied APCI technique for peptide analysis (c.f. chapter 3.1) additional research (e.g. ESI-HRMS/MS) will be necessary to verify this assumption and to elucidate the structure of the ergopeptides.” (3.
