Ankle, calf, and circulatory conditions require modern medical care. Vascular medicine, sports medicine, and orthopedics are the relevant disciplines. CrystalStones.com describes the classical mapping; we do not recommend using it for medical timing. If you have ankle pain, calf swelling, or circulatory symptoms, see a doctor, calf swelling in particular can indicate serious conditions like deep vein thrombosis.
How does Aquarius map to the body?
Aquarius rules the calves, ankles, and (in many sources) the circulatory system, the body's distribution and lower-leg structures.

Classical source
Manilius; Culpeper
The mapping
What the tradition mapped
Classical melothesia assigned Aquarius the calves and ankles, and later sources add the body's distribution networks on symbolic grounds. Modern anatomy does not use this mapping.
History
What this historically meant
Aquarius in classical melothesia governs the calves and ankles, the body's lower-leg structures, the joints that carry the body's full weight. The circulatory system association is sometimes added in later sources, on the symbolic ground that Aquarius (the Water-bearer) governs the body's flowing distribution networks.
Saturn rules Aquarius in classical astrology, Uranus only since 1781, by modern convention. Renaissance practitioners would have considered Saturn-ruled herbs for ankle and lower-leg complaints, particularly rheumatic conditions.

Medical astrology is a historical symbolic system, a real and well-documented chapter in the history of Western astrology, not medical advice. The classical rules (Manilius, Culpeper, Hellenistic and Renaissance practitioners) are described here for their cultural and reflective interest. CrystalStones.com does NOT recommend timing surgery, medication, fertility decisions, or any other medical care around moon signs. If you are facing a medical decision, talk to a qualified physician. The classical rule is symbolic; your doctor is not.

Questions
Frequently asked questions
Why did the classical sources give Aquarius the ankles?
Symbolic logic: the ankles are the body's lowest weight-bearing joints, just above the feet (Pisces). Aquarius, the Water-bearer, also governs the body's flow-distribution networks in later sources.
Which crystals has tradition paired with the Aquarius region of the zodiac body?
Amethyst, Labradorite, and Clear Quartz are the contemporary symbolic pairings, chosen for Saturn-Uranus resonance and for the sign's flow-and-network symbolism. Symbolic only.
What did classical practitioners believe about the ankles and the Moon in Aquarius?
Classical practitioners avoided elective work at the ankles while the Moon transited Aquarius. Modern medicine does not use the rule. Talk to your surgeon.
