June just seems to be flying by. This past weekend was Father’s Day in the United States (happy Father’s Day to all of you out there), and this week also marks the third year Juneteenth is a federal holiday in the Unites States! Aside from all this, June is Pride Month. My hope is that over time our societies continue to become more accepting of all the people and voices that comprise them, and that equality someday will truly be a reality instead of an ideal.
This week is also a tremendously important seasonal shift with Summer Solstice arriving today, June 21st, at 10:58am Eastern Daylight Time. At that moment, the Northern Hemisphere reached the astronomical Summer Solstice with the North Pole will at its maximum tilt (about 23.5 degrees) toward the Sun, resulting in the longest day and shortest night of the year. This means that tomorrow the days will slowly start getting shorter, heralding the cosmic transformation from Yang to Yin that has just been triggered.
In addition to being one very important moment in time, the Summer Solstice (Xia Zhi 夏至) is also the name of the seasonal node that starts today. This node marks the apex of Yang in the natural world as well as the rebirth of Yin that will eventually culminate with the longest night on the Winter Solstice in December. In relationship to the times of day, Summer Solstice corresponds to high noon, the Wu (午) hour, and is the time of the Heart channel. When we break down Summer Solstice into the smaller five-day periods of time, it includes the time periods know as Deer Shed Antlers (Lu Jiao Jie 鹿角解), Cicadas Begin Singing (Tiao Shi Ming 蜩始鳴), and Pinellia Grows (Ban Xia Sheng 半夏生) In Japan the names for the 72 Material Manifestations (七十二物候) differ slightly. The names of these three mini seasons for the Japanese are Prunella Dries (乃東枯), Irises Bloom (菖蒲華), and Pinellia Grows (半夏生 - this one is the same as the Chinese calendar). Notice that this time is when Ban Xia is growing, the king of drying damp and getting rid of phlegm turbidity (a Yang herb to treat a Yin pathology). Likewise, in China this is the time of year to harvest Aconite (Fu Zi 附子) to enhance its Yang nature.
In Yijing (I Ching) symbolism, this time period is represented by hexagram 44, made up of Qian-Heaven trigram (3 solid yang lines) over Xun-Wind trigram (1 broken yin line under 2 solid yang lines). Thus, the complete hexagram is 5 solid Yang lines over one broken Yin line at the bottom – Yin is being birthed once again. One of the translations for the name of Hexagram 44 is “The Queen,” also showing that this time of year begins the transition towards returning inward to the hidden, the Yin, the Blood, and the Dark Mother that is referred to in the first chapter of the Dao De Jing.
Practically speaking, although this is a time of transition to Yin, this is still a hot and damp season (although this year it seems to be a little less hot than usual in NJ). Thus, the first health recommendation for Summer Solstice is to focus on clearing summerheat and draining dampness. For example, various skin problems due to external contraction of summerheat damp are commonly seen now. It is also common to see other symptoms of summerheat strike such as malaise, fatigue, low-grade fever or heat effusion, low-grade headache, nausea, etc… There are several ways we can help ourselves as well as our patients when they present with summerheat damp symptoms. First, is to regulate diet, which we will discuss more below. We can also counsel basic lifestyle recommendations, such as dressing appropriately to the weather (such as wearing light clothes made of natural materials that breathe well), staying in shade in the midday when temperatures are highest, and drinking plenty of light and clear fluids. This is especially important for our older patients, since as we age we lose the normal ability to adapt to more extremes in temperature. Furthermore, seniors are more likely to be on prescription medications or may have chronic medical problems that inhibit perspiration or make extremes of temperature less tolerable. Some medications also increase sensitivity to sun raising risk of sunburns (examples include tetracyclines, quinolones such as Cipro, Celebrex, and some chemotherapeutic agents).
The next recommended “to do” during Summer Solstice is Shui Hao Zi Wu Jiao 睡好子午交. This means sleep well during both the Zi and Wu hours. Certainly, sleeping well is something we should be doing all year long. Zi and Wu refer to the time periods of midday and midnight, with Zi being the 11pm – 1am hour, and Wu being the 11am – 1pm hour (to be adjusted for standard time in locations that observe daylight savings time). In general it is important to get into bed before the Zi hour. Remember, the Zi hour is the time of transition from Yin to Yang, representative of the Winter Solstice. After this time period our bodies are already in a state of Yang expansion, the movement contrary to good sleep. Getting to bed and sleeping through this hour ensures that we really rest, that we really go into the state of storage that replenishes our vital substances.
The Wu hour is also a time of transition, and like the Summer Solstice, represents the change from Yang to Yin. The traditional recommendation is to take a short nap during this time to harmonize the body with this movement of Yang to Yin. That said, the recommendation is just a short nap of maybe only 30 minutes time (this is just the beginning of Yin after all). After that, don’t linger. Get up and back to normal activity.
Diet for Summer Solstice
As already mentioned, Summer Solstice is the time of transition from Yang to Yin in the natural world. That said, Summer Solstice is still a time of damp and heat in many places. Therefore, the basic strategy of clearing heat and draining dampness can help guide us in our diet strategy. It is important to keep in mind that during summer over-sweating and prolonged exposure to heat can deplete the Qi and fluids of the body. So, once we are clear of heat and damp, if there is vacuity we can focus on supplementation. However, since this is a hot time of year, cool supplementation is best.
In summary we can generalize this is the time to eat foods that clear heat (especially summerheat), drain dampness, nourish the Qi and boost fluids. Examples include cucumber, winter melon, luffa, tomato, honeydew melon, star fruit, peach, plumb, and mung beans. This is also a good time to eat bitter melon (ku gua 苦瓜). When I lived in Okinawa as a graduate student, bitter melon was a basic staple of food since Okinawa is a very hot and damp climate.
Here’s a formula from the Zun Sheng Ba Jian (遵生八箋) – the Eight Treatises on Following the Principles of Life. Written by a scholar by the name of Gao Lian at the end of the Ming Dynasty (1368-1644), the text is an almost encyclopedic collection of all manner of Nourishing Life (養生) recipes, techniques, theories, etc… This is a seasonal formula for summer from this text.
Cardamom Powder 豆蔻散
Ingredients:
Cao Dou Kou 草豆蔻 120g (toast until yellow together with 120g of fresh ginger, then remove the peel for use)
Mai Ya 麥芽 300g (dry fry until yellow)
Shen Qu 神曲 120g (dry fry until yellow)
Zhi Gan Cao 炙甘草 120g
Pao Jiang 炮薑 30g
Grind all ingredients to a fine powder. Take a small amount daily with water or tea. During summer as heat and dampness increases, occasionally this will negatively affect people’s digestive function and appetite. This formula opens the Stomach, increases appetite, treats abdominal distension and is particularly useful if weather is cooler or damper than usual.
