Medicinal Properties of Arba’at HaMinim

‘Sukkot in the Synagogue’ by Leopold Pilichowski (c. 1894)

As we continue to celebrate Sukkot this week and “shake” our arba’at haminim, it is worth exploring the properties of these unique four species. One of the intriguing things about them is that they all happen to be prominent players in medicine. Perhaps most well-known is the bark and leaves of the willow tree (the aravot of the four species), which is the original source for what is today aspirin. The active ingredient in aspirin is acetylsalicylic acid, a synthetic variant of salicylic acid found in high quantities in willow trees. Incredibly, archaeologists have found that teas made from willow were used medicinally as far back as ancient Sumeria (birthplace of Abraham) and ancient Egypt. The ancient Greeks used it to bring down fevers, and it was a staple medicine among Native American tribes.

It was in 1853 that French chemist Charles Frédéric Gerhardt first synthesized acetylsalicylic acid in the lab. The problem was that these types of medicines were very hard on the stomach. In 1897, a Jewish chemist named Arthur Eichengrün, working for Bayer, invented a new process for producing and purifying acetylsalicylic acid. This one was much easier on the stomach and worked extremely well. Thus, aspirin as we know it was born, and is today the most widely-used drug in the world. Things didn’t turn out so well for Eichengrün, though. When the Nazis came to power, they could not tolerate a Jewish inventor for aspirin, so they wiped his name from the history books and instead made sure to credit German scientist Felix Hoffman with the invention. Eichengrün was arrested and sent to a concentration camp. Thankfully, he survived the Holocaust. Altogether, Eichengrün held 47 patents, and also invented Protargol, which was the standard treatment for gonorrhea for over 50 years.

The way that acetylsalicylic acid actually works in the body was only discovered in 1971. It’s main mode of action is by blocking a family of enzymes called cyclooxygenases (COX), key players in the inflammatory pathway. By inactivating these enzymes, aspirin is able to reduce pain and inflammation. It also helps to block the formation of blood clots. More recently, acetylsalicylic acid has been shown to help improve the function of mitochondria—those tiny organelles within each of our cells that powers our bodies.

One of the main uses of aspirin today is to help treat and prevent heart attacks and heart disease, which is the world’s number-one killer. The main cause of heart disease is poor diet, particularly high cholesterol and saturated fats, as well as high sodium which increases blood pressure. Another major cause is smoking. Fittingly, our Sages taught that the aravot parallel the mouth, and resemble the shape of the lips. The purpose of the aravot is to both spiritually rectify the sins of the mouth, as well as to remind us to control what goes in (and out) of our mouths. We ask every morning in birkot haTorah that God should make words of Torah “pleasant-tasting” in our mouths (וְהַעֲרֶב נָא יְהֹוָה אֱלֹהֵֽינוּ אֶת־דִּבְרֵי תוֹרָתְךָ בְּפִֽינוּ) and this ties directly to the mouth-like aravot (ערבות). We should increase the use of our mouths for words of Torah, and decrease its use for the oral vices that end up harming people.

Myrtle Leaves

The other leaves in the four species, myrtle or hadassim, also happen to contain high amounts of salicylic acid. Additionally, they are rich in various antioxidants. Those mitochondria mentioned above use the oxygen we breathe in the production of energy. More specifically, producing the energy molecule ATP requires the movement of hydrogen ions. To keep those hydrogen ions moving in the right direction, oxygen comes in to bond with them, and pick up a pair of electrons, too, generating water. This is the main reason for why we need to breathe! The primary role of oxygen in the human body is to be an “electron acceptor”, picking up some electrons and some hydrogens so that energy production can continue.

The Electron Transport Chain within the mitochondria in our cells produces most of our energy. Water is generated at Complex IV, where oxygen comes in to serve as the final electron acceptor. Energy (in the form of ATP) is produced at the Synthase pump, driven by the movement of hydrogen ions. 

In this process, however, sometimes the oxygen molecules don’t bond properly, and form dangerous “reactive oxygen species”, or “oxidants”. These free radical oxidants can attack other structures within the cells, causing cellular damage and “oxidative stress”, strongly linked to aging and cancer. Thus, we need anti-oxidants to neutralize these troublesome free radicals. This is why you might see “antioxidants” advertised on the labels of health foods, cosmetics, and other commercial products. The leaves of hadassim naturally contain very high levels of antioxidants.

Throughout history, myrtle leaves have been used medicinally. Today, they have two main uses: One, the essential oil of myrtle is used in aromatherapy and to treat lung illnesses. Myrtle helps to open up the airway and reduce inflammation in the lungs. Second, it is used to treat and help prevent the spread of HPV, a sexually-transmitted disease. It is interesting to point out that our Sages paralleled the hadassim to the eyes. As we read in the Shema, God warns us not to follow after the lustful desires of the heart, which follow the eyes that are easily enticed by inappropriate sights and images. The Torah specifically uses the word zonim, implying sexual immorality, which begins with inappropriate sight. Thus, the use of myrtle leaves in treating sexually transmitted diseases is all the more appropriate!

Date Palms

The kapot tamarim, or lulav, is the “spine” of the date palm, and our Sages paralleled it to the spinal cord of the human. Both the fruit of the tree, and the “hearts of palm” of the lulav are highly nutritious. Their high fibre content was historically used to treat constipation. Recall that the Rambam held constipation to be a major root of poor health, writing in the Mishneh Torah that “Whoever sits comfortably and takes no exercise, holds his waste or has ‘hard’ innards, even if he eats all the best foods and follows the top medicine, all his days will be full of pain and his strength will decline.” (Hilkhot De’ot 4:14-15)

Mitochondria under a microscope.

In ancient Israel, the date palm was the source of honey. As is well-known, when the Torah speaks of Israel being a land flowing with “milk and honey”, it is referring to date honey, not bee honey. Honey is about 80% sugar, our body’s main energy source. In fact, those electrons in the mitochondria mentioned above, which drive the “electron transport chain” to produce our ATP energy, are extracted from sugar! We now see how the main ingredients in aravot, hadassim, and lulav all play a big role within our mitochondria, driving our biological life force.

Dates are also very rich in potassium—50% more than in bananas! Potassium ions play the most important role in the transmission of nerve signals. Every nerve conduction requires an exchange of sodium and potassium. So, it is appropriate that the lulav is compared to the spinal cord, the most important bundle of nerves in the body. Sefer haBahir, one of the most ancient mystical texts, states that not only does the lulav parallel the spinal cord, it also parallels the letter nun sofit (ן), which resembles a spinal cord. The value of the nun is 50, alluding to the 50 Sha’arei Binah, “Gates of Understanding”.

Etrog

Finally, we have the citrus etrog. As expected, it has a very high vitamin C content, typically considered the most important vitamin in the body. The greatest champion of vitamin C was Nobel Prize-winner Linus Pauling. (Pauling is actually one of just four people to win two Nobel Prizes!) He was also ranked the 16th greatest scientist of all time. It was Pauling who first proposed that vitamin C can combat cold and flu infections. He later took it further and suggested vitamin C as a cure for all kinds of ailments, including cancer. His main work was in using vitamin C to treat heart disease and angina. Today, this method is still referred to as Pauling Therapy, though it remains controversial. Nonetheless, it is quite fitting since, of course, our Sages stated that the etrog parallels the heart!

The other known medicinal use of the etrog (or “citron”, in English) is as an antibiotic. Specifically, it is the rind of the etrog which is thought to contain strong antibiotic properties. This would help to explain why the Torah calls the etrog a pri etz hadar, one of the classic explanations of which is that it is a “long-lasting” fruit that doesn’t spoil quickly. Spoilage is caused by a number of factors, one of which is the proliferation of bacteria. By containing an antibiotic in its rind, the etrog stays fresh much longer than other fruits.

Related to this is that the etrog has an insecticide property. The ancient Greek scholar Theophrastus (c. 371-287 BCE) wrote that it was common to keep etrogim around clothes to repel moths and bugs. Similarly, Pliny the Elder (c. 23-79 CE) wrote in his Natural History that the etrog “is very useful in repelling the attacks of noxious insects.” (A useful tip for those of us who have to deal with wasps and mosquitos in the sukkah!) This is yet another reason for the etrog remaining fresh and long-lasting. Both Theophrastus and Pliny note how the etrog bears fruit all year round, which ties to the final reason for why the etrog is identified as the Torah’s enduring pri etz hadar. Lastly, Pliny mentions that pregnant women would chew on etrog seeds to prevent morning sickness and nausea, fitting neatly with the notion that the etrog is a potent segulah for fertility.

In short, just as the four species are physically healing, they are even more so spiritually healing. As the Zohar famously states, this lower material world is only a reflection of the higher spiritual worlds. Thus, if the four species have potent medicinal and chemical properties in this lower world, their root in the spiritual realms must be all the more powerful and effective. Something to keep in mind as we fulfil each day of Sukkot the mitzvah of netilat lulav.

Chag Sameach!

Is Playing Sports a Mitzvah?

In this week’s parasha, Va’etchanan, we read the famous words: v’nishmartem me’od l’nafshotechem, “Guard your souls very much…” (Deuteronomy 4:15). The plain meaning of the passage within which these words are found is to be careful not to descend into idolatry, nor to make any sculptures or images of any figures that might be idolatrous. However, since ancient times the phrase to “guard your souls very much” has also been used to mean that it is our obligation to stay healthy and in good physical shape. If the body is not healthy and dies, then the soul will depart it. Having a healthy soul therefore requires maintaining a healthy body, and a pure soul requires a pure bodily vessel.

Interestingly, it was the great Hillel who first pointed out the connection between the prohibition of idolatry and the mitzvah of taking care of one’s body. The Midrash (Vayikra Rabbah 34:3) recounts how Hillel once took leave of his students and they asked him where he was going, to which he replied: “To do a mitzvah!” They asked which mitzvah, and he replied that he was going to the bathhouse. The puzzled students questioned him: is taking a bath a mitzvah? Hillel replied affirmatively, and explained: if all the statues and icons erected in public places needed to be constantly washed, and they are nothing but man-made objects depicting flesh-and-blood kings and nonsensical idols, how much more so must we keep our bodies clean since we were made in the image of God? And this is the deeper meaning behind King Solomon’s words gomel nafsho ish chassed (Proverbs 11:17), that a kindly or pious man makes sure to take care of his soul.

Our Sages had much to say about maintaining good health. For instance, in Gittin 70a, we are taught that there are 8 things that are healthy in small quantities, but harmful in excess. These eight are: travel, sexual intercourse, wealth, labour, wine, sleep, baths, and bloodletting. When it comes to the latter, in those days bloodletting was a popular therapy and it was thought that draining out some “old” blood will stimulate the production of new, healthier blood. There may be something to this, with recent research showing that bloodletting may indeed have been beneficial, and was possibly even effective against bacterial infections. Today, bloodletting is no longer done, but there may be a way to reap the same benefits (and do a double-mitzvah) by going to donate blood. Continue reading

The Guardian Angels of Israel

‘Abraham and the Three Angels’ by James Tissot

This week’s parasha, Vayera, begins with Abraham being visited by a trio of angels. Jewish tradition holds that these angels were Michael, Gabriel, and Raphael. The Ba’al HaTurim (Rabbi Yakov ben Asher, c. 1269-1343)—famous for his numerological commentary—points out that the words “And behold three…” (והנה שלשה), referring to the three angels, has the same gematria (701) as “these are Michael, Gabriel, and Raphael” (אלו מיכאל גבריאל ורפאל).

Rashi (Rabbi Shlomo ben Itzchak, 1040-1105) comments that each angel came for a specific mission: Michael to bless Abraham and Sarah with news of their impending child; Gabriel to destroy Sodom (which happens right after in the Torah); and Raphael to heal Abraham from his circumcision (which happened just before). The root of Gabriel is gevurah, “strength” or “restraint”, which is why Gabriel often appears in difficult situations, or acts of destruction. The root of Raphael is refuah, “healing”, so he appears whenever a recovery is required. Michael is the guardian angel of Israel, as we are told explicitly in Daniel 12:1.

These three angels regularly appear together. They were originally depicted as the highest of the angels in the Heavens. Later mystical literature would place others above them (namely Metatron). Still, the trio of Michael, Gabriel, and Raphael remain the most well-known. What else do we know about them?

Michael: Priest and Saviour

In one mystical passage, the Talmud (Chagigah 12b) outlines the Seven Heavens. The first is called Vilon (“curtain”) and simply refers to the atmosphere stretching over the Earth like a curtain. This is the place of clouds and weather, serving no particular spiritual purpose. Then comes the Rakia, the vast realm beyond Earth’s atmosphere that includes the Sun, moon, and all the stars and planets, ie. outer space. The third Heaven is called Shechakim, which we learn from other sources is the interface between this physical universe and the spiritual realms beyond. The Sages sometimes metaphorically describe it as being composed of millstones, or slabs of pure marble. The Talmud says this is the source of the manna that the Israelites ate in the Wilderness.

The fifth, sixth, and seventh Heavens are called Ma’on, Machon, and Aravot, but it is the fourth Heaven that is of particular interest for the present discussion. Here one will find the illustrious Yerushalaim shel Ma’alah, the Heavenly Jerusalem, a spiritual version of the Jerusalem below. Mirroring the one on Earth, there is a Temple up there, too, and it is Michael who serves as its High Priest.

Michael also serves as “Prince of Israel” and our Heavenly Guardian. In this role, he stands opposite Samael, the Heavenly “Accuser” who seeks to harm Israel. Hence, Michael stands at the gates of Heaven, admitting the righteous and guiding their souls. Similarly, he was Israel’s guide during their forty years in the Wilderness, being identified with the “angel that will go before you” (Exodus 23:20, 32:34), as God has promised (see Midrash haNe’elam, Beresheet 2).

Naturally, Michael is a great saviour for the Jews. It was he who saved Abraham from the fiery furnace (Beresheet Rabbah 44:16), and protected Sarah when she was abducted by Avimelech (Pirkei d’Rabbi Eliezer 26). In one intriguing Midrash (Yalkut Shimoni, Beresheet 134), we learn that Michael saved the baby that was born from Dinah’s rape by Shechem. Michael took the baby to Egypt, into the care of a wealthy childless couple. That wealthy man was Potiphar, and the adopted baby was Osnat, future wife of Joseph!

Gabriel and the Founding of Rome

When it comes to Joseph, it was Gabriel that helped him throughout his journey. According to the Talmud (Sotah 36b), Gabriel taught Joseph overnight (or perhaps “uploaded” into his brain) knowledge of the seventy languages, which allowed him to become viceroy of Egypt. Gabriel also taught Joseph all of the esoteric mystical wisdom of the Torah (while Raphael taught the same wisdom to Isaac; see Ravad on Sefer Yetzirah).

The Talmud credits Gabriel with setting the foundations of Ancient Rome (Shabbat 56b). This happened on the very same day that King Solomon married an Egyptian princess. Although Solomon’s intensions were certainly good, his many marriages spiralled out of control, and ultimately led to his downfall. In poetic fashion, King Solomon first builds Jerusalem’s Temple, and simultaneously sows the seeds of its destruction, for Rome would go on to destroy Jerusalem’s Temple for good, ushering in an endless exile which we are still in.

Interestingly, archaeologists have found coins bearing images depicting this version of Rome’s founding. The coins show a divine being of some sort planting reeds in the Tiber River to set the foundations of the “eternal city”, just as the Talmud describes. These coins were minted in the time of Emperor Antoninus Pius, which is most fitting because the Talmud tells us that a Roman emperor named Antoninus was good friends with Rabbi Yehudah haNasi, and the two engaged in many philosophical discussions.
