Herbal archaeology roundup 3

Taking a brief break from the bad science series, I thought it was time for another botanical blast from the past. Unfortunately, as far as I know, no one is specializing in the archaeology of herbs, but here and there, some really interesting stuff is being discovered. My definition of “herbs” here isn’t limited to the strictly medicinal, because after all it’s a fine line between medicine and food (if there even is one), and when we’re talking about the very ancient past, we are lucky when we can figure out what someone was ingesting–knowing why is often beyond our ken. Let’s proceed in chronological order! (Headings are links to articles.)

Oldest evidence for fungi in the human diet

The “Red Lady” burial of El Mirón cave (Cantabria, Spain) dates to approximately 19,000 years ago and is very interesting. This individual, a woman aged about 35-40, was given special treatment. Really, anyone buried during the Palaeolithic was probably receiving special treatment, because very few graves have been found. Interestingly, a number of the burials that are known contain people who were physically unusual. That was the subject of one of my first grad school papers (sigh, good times)–but sadly that was so long ago that I don’t remember all the specific examples. An individual from a double burial at Romito, Italy had achondroplasia; and the woman from the triple burial at Dolní Věstonice, Czech Republic probably suffered from chondrodysplasia calcificans punctata (probably the milder X-chromosome-linked variant), a rare genetic disorder, “complicated by trauma and early fractures of the upper limbs.” In my research I found that a statistically significant proportion of Palaeolithic burials contained people who would have looked different, and in some cases been differently-abled, than other members of the community. (I really should have worked that up for publication because as far as I know, no one else has. There is this article that suggests these burials might be human sacrifices but since there’s no evidence for violent death/murder in these burials, I think it’s a bit of a reach to assume these people were sacrificed. But I digress.) The Red Lady was in robust good health, other than being dead, but she did show evidence of another common theme of Palaeolithic burials, which is that the bodies were sometimes covered in red ochre (iron mineral pigment). The Red Lady’s body was covered with ochre, and at some people people went back to the burial and applied more ochre to the bones. Moreover, pollen in the grave suggests that people may have left flowers there.

Moving on to the mushrooms, analysis of the Red Lady’s fossilized tooth plaque reveals that she ate fungi, making this the oldest evidence of fungi in the human diet (you can be sure it goes back further though). Remains of multiple types of mushrooms were found, including ones belonging to the Agaric family. Some agaric mushrooms are harmless, but some are majorly hallucinogenic (and/or poisonous): “There is some evidence from neolithic and Bronze Age sites in Piedmont in the Italian Alps that suggest psychotropic mushrooms were used in rituals.” Maybe their use extends even further back in time.

High on henbane in the Neolithic?

Black henbane

Black henbane

So far only a single charred black henbane (Hyoscyamus niger) seed has been found at Ilendentsi, Bulgarian, a settlement dated to around 5800 BC. However, archaeologists are tentatively speculating that the residents may have been consuming henbane, a psychotropic. Henbane is a member of the Solanaceae, a relative of nightshade, datura, and mandrake and in medieval times was used as an ingredient in witches’ “flying ointments.” In other words, they are really toxic if not used in tiny quantities–maybe that’s why they have only found one seed at Ilendentsi! Henbane was also found in pottery from the stone circle at Balfarg, Scotland, bolstering the interpretation that the circle was used for ceremonial/ritual purposes.

Scythians liked their opium with a cannabis chaser

Ornate gold cups from the Sengileevskoe-2 kurgan (South Caucasus, Russia) contained a black residue with traces of opium and cannabis. This, along with other archaeological sites, confirms Herodotus’ claim that the Scythians used cannabis, but so far as I know this is the first evidence for their use of opium (I could be wrong, because it was certainly used long before the date of the Sengileevskoe-2 burial around 400 BC).

An ancient Graeco-Egyptian hangover cure

How did you pull yourself together after a night on the town 1,900 years ago? By wearing a garland of Alexandrian laurel leaves (Danae racemosa, formerly Ruscus racemosus) around your neck. This comes from a trove of medical papyri discovered at Oxyrhynchus, Egypt. Dioscorides wrote in somewhat greater depth, recommending a topical application of pounded leaves to cure headache, and the juice of the leaves mixed with wine to sooth stomach ache, bring on menstruation, or urine. A garland of Alexandrian laurel (this time worn on the head) was still being recommended in the 16th century. Because the exact “recipe” for the garland isn’t included in any of the articles I found, but one article says “possibly” worn around the neck, I wonder if in fact it was always meant to be worn about the head–that would fit with the instructions in Dioscorides and the 16th-century herbal. According to a 2009 study published in the Journal of Medicinal Plants, Alexandrian laurel is used as a culinary spice and contains vitamins and antioxidant flavonoids. The authors found that rats receiving a high dose of D. racemosa produced more sperm,, suggesting it may be useful in treating infertility.

Medieval eye-salve cures MRSA

A recipe for treating eye infections in the 9th-century Anglo-Saxon medical text Bald’s Leechbook describes a salve made from onion, garlic, wine, and cow bile, steeped for nine days. The remedy was recreated by microbiology researchers at the University of Nottingham (they even used English wine!) and tested on methicillin-resistant Staphylococcus aureus, a.k.a., MRSA. The recipe killed up to 90% of the MRSA bacteria, and the researchers concluded that it was the combination of ingredients–rather than any single ingredient–that did the trick.

The contents of this Maya “death vase” might make you wish you were dead

The sort of thing one might see in a Maya vision. Here a spirit emerges form a serpent, which rises from a basket filled with bark paper. The paper was used to absorb sacrificial blood, usually taken from a queen's tongue or king's penis. Ow.

Meanwhile in the “New” World, the Maya were consuming some pretty potent stuff. At a site in Hondurus archaeologists discovered a vessel containing pollen from corn (maize), cacao, and false ipecac (Pscychotria emetica or Ronabea emetica)–the latter a plant which, as its species name indicates, causes vomiting. One interpretation is that the purpose was to have visions and so communicate with the spirit world. (The Maya also used chocolate enemas. Now I love chocolate, but it seems to me that is not the best way to enjoy it.) Although it’s not mentioned in the article just exactly how barfing your guts up is supposed to lead to having visions, many members of the genus Psychotria contain DMT, a psychedelic. However, some cultures have uses vomiting (and other bodily processes of excretion) as a purification, though it’s not known to have been done by the Maya. Speaking of vomit…

Ancient Cahokians were super buzzed–and really sick

Cahokia, the largest metropolis of pre-Columbian North America, was situated in Illinois directly across the river from where St. Louis would later be established. Once again, plant remains in a cup have provided evidence that locals were drinking a botanical brew–this one made from the leaves of yaupon holly (Ilex vomitoria). Once again, the species name gives a clue as the effect of this beverage, and once again, archaeologists have speculated that vomiting was part of some purificatory ritual. In this case, there is further evidence that this “black drink” was used in ritual contexts, because once Europeans arrived they recorded that men from cultures all over the American southeast drank the black drink for purification. It’s use dates back 1000 years. Aside from its nauseating properties, the holly drink contained theobromine (also found in chocolate) and 6 times as much caffeine as coffee. Those people must never have slept. I. vomitoria doesn’t grow around Cahokia, so this is also evidence for very long-distance trade networks, which is also seen in the distribution of other materials, especially ceremonial ones such as copper, shells, and iconography.

I found it very interesting that a couple of the comments on this article say that yaupon holly makes a nice tea and does not result in copious barfing. This may be a dosage issue. While a “mildly stimulating” and “intoxicating” beverage can be made from the dried and roasted leaves, the historical texts indicate that the leaves were toasted and then boiled for several hours to produce a thick decoction that inducing immediate vomiting (source).

Well, I hope you enjoyed this installment of the herbal archaeology roundup! I will continue to bring you all the herbal archaeology news–or should I say “olds”–that’s fit to print.
